Latest chemical order?

Pages: 1 .. 12 13 14 15

Lion850 - 29-9-2020 at 20:57

Yesterday I went down to Science Essentials (in Brisbane) to buy some basic cobalt carbonate and a few beakers and was given various old chems for next to nothing. I ended up with:

- Basic cobalt carbonate 500g
- Magnesium oxide AR grade, some 200g
- Calcium gluconate anhydrous 500g
- Cobalt nitrate hexahydrate around 100g, plus 2 old bottles of cobalt nitrate that got wet.
- Sodium gluconate, about 20g
- Calcium carbonate around 200g
- Sodium metasilicate pentahydrate 500g

Have to read up on gluconates and the sodium metasilicate and see what to use them for.

Since you have so many metal salts, you can try the classic chemical garden experiment.
I'm curious if the rare earth salts would work or not.

Yes, they work. Only alkali metal silicates are soluble in water.

I second that, chemical garden experiment is awesome! yes any salt should work except for Group 1 metal salts...

I ordered some adipic acid. I want to try making some cubanes when I get a chance to do some chemistry.

itsallgoodjames - 9-10-2020 at 22:32

Today I got the following

100g magnesium turnings
2000g sodium hydroxide
500g potassium hydroxide
100g menthol

As you can probably guess, I plan to make a lot of sodium metal and a bit of potassium through the alcohol catalyzed alkali metal production method. I'll have to make some dioxane at some point

Cou - 9-10-2020 at 23:15

just received:
500 mL valeric acid
250 mL octanoic acid
500 g decanoic acid

itsallgoodjames - 14-10-2020 at 06:32

Today I got 10 grams of metallic mercury. Holy, this stuff is super dense

Cou - 14-10-2020 at 21:01

Chemicals from mario840:
500 g phenol
500 g cyclohexanol

teodor - 16-10-2020 at 03:11

1000 g KMnO4 - for synthesis of carboxylic acids, also as a source of hydrated MnO2.
100 g Sn - for making SnCl4
150 g CaCl2
100 g Na2S2O3

woelen - 19-10-2020 at 02:12

I received the following chemicals:

- 300 grams of inositol for making rhodizonic acid and potassium rhodizonate
- 250 grams of benzoic anhydride for doing aromatic ester experiments
- 250 grams of copper sulfate, analytical reagent for very sensitive complex/coordination experiments
- 25 grams of 99.9% zinc arsenide, (no experiments planned yet, maybe make a tiny tiny little bit of AsH3 for Marsh test or something like that, need to think over the setup). Triple packed (little glass vial, wrapped in plastic bubble foam, put in second larger plastic jar).
- 50 grams of 99.9% zinc phosphide, for easily making small amounts of PH3. PH3 is quite interesting stuff. It is very toxic, but has no serious long-term effects and when handled with respect, its toxicity risk is comparable to the toxicity risk of H2S (it is more flammable though, but it does not numb your sense of smell at higher concentrations). Just work outside and with small amounts.

So, you also became interested with PH3 - it is very interesting what you will find.

teodor - 21-10-2020 at 07:30

75 g Cd metal and 80 g Bi metal - for study chemistry of these metals as well as cation samples for qualitative analysis
2g Ag - for preparation of standard solution AgNO3 (for titration)

Herr Haber - 21-10-2020 at 11:33

100 grams of Rhodamin B were transfered from a ziploc bag to HDPE vial 10 days ago.
Red spots have started to appear in unexpected places. Darn that thing can fly !

10 grams Luminol
200 grams Fluorescein

Damn lol just how much stuff do you have? I keep seeing your posts around like "Just got 2 kg of Zr metal!" That's some dedication! But I prefer bigger amounts myself, so I get you... Is it more like a collection or are you just always working in the lab?

Herr Haber - 21-10-2020 at 19:48

2 kg of Zr metal ? No, not that much

But I do have it in every form, several of them for display. Onyxmet and Chemcraft are great sources when you want beautiful or pure.

You're probably thinking about the 2 kg of Hg I'm supposed to get this weekend from someone who wants to get rid of it. Dont have it in my hands yet... Will definitely do a chloralkali cell just to tick that box and enjoy the sight until I get bored. All the products are easily obtainable otherwise.

I'll probably have a pretty picture to post with one of the dyes and a few other ones of something quite beautiful that grew in the reactor I use to dissolve silver.

Trick or treat !

Herr Haber - 23-10-2020 at 13:22

Yay, just picked up this merury bottle from a friend who had been holding onto it for 43 years.

It is dirty as you can see on the bottle (used to be Merbromin, ah the irony!). Buuuut it's almost 2 kg and I'm not one to look into the mouth of a gift horse

itsallgoodjames - 28-10-2020 at 14:52

Just recieved:

200g magnesium turnings

1kg of sulfur

500ml 35% hydrogen peroxide

4L 32% hydrochloric acid

Herr Haber - 28-10-2020 at 21:02

10 platinum.

Belowzero - 31-10-2020 at 11:34

Got myself 20Gr of PalladiumChloride reagent grade for 25$!!.
And 0.5 Kg of Mercury which I never owned before , magical stuff!
I was aware of its density but it is still the weirdest thing to hold such a tiny amount weighing that much.

Oh and 2Kg of analytical grade KOH for next to nothing.

Still waiting for my delivery of Vanadiumpentoxide which will be used as catalyst (contact process)

I was stunned and confused too, when I realized that it was this old man selling off his basement stock of chemicals it started to make sense , either he didnt know what he was selling or the last time he checked the palladium price was 1961.
Not sure but I am absolutely positive it is what is says on the original bottle.
It usually sells north of 115$ per gram!!

Has anyone ordered sodium metal (let's say 100 g) from Onxymet or Limac to the USA? Was it a pain in the ass dealing with customs? I know that sodium is one of the watchlist chemicals but I don't know what this means in terms of practically importing it. Their prices are so much lower than domestic suppliers...

Cou - 1-11-2020 at 15:59

100 grams of p-TsOH

I found that while sulfuric acid causes benzyl alcohol to polymerize, forming a tar and causing bad yields, p-TsOH (or using sulfuric acid + toluene as the dean-stark solvent) doesn't cause tar formation.

Phthalic anhydride. Luminol and phthalocyanines are on the cards

500 g bromobenzene
500 mL diethyl carbonate

Hoping I can do some fun grignard reactions at home. Phenylmagnesium bromide is the easiest grignard reagent to make. Not carcinogenic like alkyl halides, commonly prepared in undergrad teaching labs.

[Edited on 11-7-2020 by Cou]

Fyndium - 7-11-2020 at 01:03

Finally restocked some 98% sulfuric acid.

[Edited on 11-7-2020 by Cou]

diethyl carbonate is a fun reagent because it can be used to make tertiary alcohols from only a grignard reagent.

the alcohol is a tertiary alcohol with the alkyl group copied 3 times.

Tsjerk - 8-11-2020 at 02:56

Nice, what are you planning to do with the triphenylmethanol?

Cou - 8-11-2020 at 14:07

i think triphenylmethanol is a cool molecule itself so i just wanna make it for the hell of it.
I also want to try making esters of it, such as trityl acetate. I think you can do fischer esterification because triphenylmethanol doesn't dehydrate.

j_sum1 - 18-11-2020 at 19:18

Some things are just destined to bring a smile.

woelen - 19-11-2020 at 02:32

That's a really nice one! Sad that this is not possible anymore in the EU

teodor - 19-11-2020 at 03:00

CaO, 250g - for gas & alcohol drying
Acetylchlorid, 500 ml - for organic synthesis & experiments with dehydration of some metal chlorides
P4O10, 100g - as a drying agent
FeCl3, 250g - anhydrous, for continue experiments with FeCl3/organic layer extractions (I've got some interest in family of [FeCl4]- compounds)
Fe powder < 100um, 500g - just as a source of pure Fe
1-Propanol, 1-Pentanol, 1-Octanol, 1-Decanol (250ml each) - they were missing in my alcohols collection. So, now I have all isomers of 1-4 atomic alcohols, 2 isomers of penanol, but hexanols-heptanols as well as 9 atoms are still missing.
Salicylic acid, 250g - for salicilate esters and phenol synthesis

I've got hexanol, heptanol, sec-octanol, dodecanol, tetradecanol (mirystyl alcohol) and hexadecanol if you were interested in widening your collection

Thank you, but my next purchase will probably be some chromium compounds, I need CrO3 for sure - it is waste of reagents to make it from K2Cr2O7 and H2SO4 as I did before, especially now ... and I am looking for best quantity/price for it (purity is not so important).
Also some "blue" Cr(III), most obvious KCr(SO4)2·12(H2O) but I am doing a lot of experiments with Cr now so probably depending on availability will get interest in other compounds, the purity is important in this case, as a reference ...
Also I have pain in the ass (and the lungs as well) crystallising Co(NO3)2, so for good price I would probably just buy some ... as well as probably some other (definitely Cr) metal nitrates, even if I can make them they prefer to crystallise by seed crystals only, so I need few samples for seeding ... the price is important, also I would prefer to buy, let say, 5 different samples 10g quantity each (different metals) than 1 sample 50g.
Well, also I am preparing standard solution for acidimetry/alkalimetry etc, so need some reference compounds with best purity, and I am not sure what is available on the market. I've made some 0.1N AgNO3 last week using pure Ag which people sell for element collectors , but I also need sodium oxalate and Mohr's salts (as standards) which I've made by myself but purity ... well, I am not sure how good is it for precision work, I mean I did crystallisation by myself and now need use it as a reference by weight.

So, if somebody have idea/offers of anything I mentioned, just U2U me.

AvBaeyer - 22-11-2020 at 19:22

Ordered some oxalic acid advertised as "100% pure and anhydrous" on Amazon. I wanted to be certain that it was truly anhydrous so I checked the melting point. It started to melt around 95C and finished at 102C. Even more water than dihydrate given the mp characteristics. The anhydrous form should melt around 189C. When it sounds to be too good to be true, it usually is. Buyer beware.

AvB

woelen - 23-11-2020 at 10:50

Many times I have seen chemicals sold as "anhydrous". In most cases it just means that the chemical is a dry powder or free flowing crystalline solid. I even once saw copper nitrate being sold as anhydrous on ebay, it was just Cu(NO3)2.3H2O, but it was a nice dry solid, while copper nitrate frequently is moist, due to its hygroscopic nature.

JJay - 28-11-2020 at 17:39

I didn't place any new orders, but my adipic acid finally arrived. Also, my sodium borohydride finally made its way to my lab.

I'm going to be traveling for work for the next two months, but I'm definitely looking forward to getting back into chemistry when I get back.

woelen - 16-12-2020 at 11:25

I purchased 100 grams of arsenic sulfide, As2S3, for the amazingly low price of just $9.99 (appr. EUR 8.50), including shipping. The order arrived last week and today I tested its purity. I am really impressed about the purity of this product of natural origin. This material easily dissolves in dilute warm NaOH, and the solution is completely clear, and very pale yellow. No insoluble crap or turbid solution as one normally would expect from natural minerals.

This opens up relatively safe aqueous arsenic chemistry for a very affordable price. Water-soluble arsenic compounds are quite hard to obtain, so if you are interested in arsenic chemistry AND you can work cleanly, then I would grab 100 grams of this as long as it lasts.

https://nl.aliexpress.com/item/33017545866.html

If you use this material for experimenting, be careful. This material is TOXIC, especially when it is dissolved!! Avoid reactions with strong reductors, where H2 can be formed. As a side reaction, small amounts of AsH3 may be formed, besides H2!! So, unless you are absolutely sure about your safety measures, do not use with zinc or magnesium in acidic solution, or with Al in alkaline or acidic solution, nor with NaBH4!

The seller calls this stuff realgar and also he also uses the word "orpiment". This is not realgar. Natural crystalline realgar is a bright scarlet red compound, As4S4. This yellow material is orpiment. Natural orpiment may contain realgar as impurity, but fortunately my sample does not contain that.

My calcium acetylide has finally arrived from the UK! I'm ecstatic. Hopefully I have time to make copper and silver acetylides this weekend. A few days ago I also received some potassium permanganate

woelen - 22-12-2020 at 05:21

I now also ordered 100 grams of realgar, the red arsenic sulfide As4S4. Also from AliExpress for a really low price.

https://nl.aliexpress.com/item/1005001309126232.html

It will take a few weeks before it arrives, but I am not in a hurry. Always good to have a little more of this as well. I now only have 10 grams or so of this compound (very expensive on eBay).

Can you please keep us updated on that (quality, appearance...)? I've been thinking about buying it ever since it appeared for sale 4-5 years ago, but never did. I lowkey fear I'll get some half-assed solid filled with sand or soil. I know it's not an ACS chemical but I'd rather not buy a bag of yellow sand.

woelen - 23-12-2020 at 04:04

For this one I can say that I was really nicely surprised: https://nl.aliexpress.com/item/33017545866.html
This is really pure, almost lab grade! This is not realgar, but orpiment, As2S3. I really recommend this!
I used it for my newest experiments on my website about arsenic chemistry.

Here follows a picture of the material I have in my hands:

I do not yet know about the realgar I ordered yesterday. I'll tell over here about the quality of that material when I receive it.

[Edited on 23-12-20 by woelen]

valeg96 - 23-12-2020 at 04:14

Yes, that orpiment is exactly what I set my eyes on. There's also some cinnabar that looks really nice on Aliexpress, but is much more expensive (ca. 30€/100g)

woelen - 23-12-2020 at 06:44

I just did a nice energetics experiment with the orpiment. I crunched some and carefully mixed it with some KClO3. When ignited, this mix burns very fast. Do NOT inhale the smoke! I only did this experiment at 100 mg scale or so. No weighted amounts, just half a spatula full of orpiment and a spatula full of KClO3 and carefully mixed with a soft twig. This definitely is not a bag of sand or soil!

[Edited on 23-12-20 by woelen]

valeg96 - 23-12-2020 at 09:21

I don't deal with anything that involves per/chlorates or anything energetic, so there's no way I'd do that. I wish there was a safe and quick way to turn it into a decent salt or the oxide. Sadly, burning it can't be done at home. I remember seeing a medical report in a toxicology book about a man who tried to make and sell homemade arsenic pigments in the 1840s and killed off his whole household overnight with the fumes. I assume he did something like that, as As oxides are fairly volatile and sublime easily.

Edit: your feedback and article convinced me. After like 6 years, I just ordered it myself (the ground up orpiment).

The 'stones' are covered by orange powder (pararealgar, an allotrope, which is formed on exposure to light). I crushed some of the material and dissolved it in NaOH. It dissolves, as shown in my webpage, and gives dark brown, nearly black, elemental arsenic. So, this realgar also is a good buy for a good price!

Lion850 - 20-2-2021 at 01:45

Today I got the following - most old stock at low prices and some free.
- Chloroform 500ml
- Selenium powder 25g
- L-Cystine 500g
- Aluminium potassium sulphate (potash alum) 500g
- Lead dioxide 500g
- Potassium chromate 500g
- Copper (ii) sulphide 100g
- Sodium borohydride 100g. This is old stock: when I saw the rusty tin I was sceptical of the condition of the contents but the product is in a plastic bag in the tin and the inside of the tin is in good condition. Anyway, NaBH4 is not easy to get hold off so I was not going to pass it by

My cousin works as maintenance at a large poultry plant owned by a real recognizable brand from Arkansas, and bless his heart, he brought me a five gallon poly bucket of 98% H₂SO₄. I hear that there is some quite concentrated H₂O₂ there too..............

Now I have to SAFELY get it into smaller, manageable containers.

Just purchased 1.5 pounds of 1,3-dibromo-5,5-dimethylhydantoin (DBDMH). Even though it has been off the market for a few years there still are a few places that have it. It does take a good bit of searching to find it.

I have to highly recommend S3 chemicals, a Germany-based company. They sell also to individuals some limited amount of reagents.
http://es-drei.de/
They ship to EU too.
Shipping cost to the neighboring country (from Germany to Czech republic) was 16,90 EUR for 9,5 kg parcel using DHL courier.

I just ordered 250ml of azeotropic nitric acid from chemship1978. I'll post a picture when it arrives. I know it's not the liters that some people have, but it's exciting, as I can finally do silver chem on scales larger than a few ml.

DraconicAcid - 16-3-2021 at 14:53

I got 50 g of gallium, some for playing with, and some to use as a replacement for mercury in amalgam reductions.

Fery - 17-3-2021 at 06:51

Hi DraconicAcid, pls post then your experiments, I'm very interested in them. I've bought a little of gallium as you, but it is yet only sitting in the vial, not yet time either experience to perform these reductions. I've bought also 1 kg of Sm as an alternative reducing agent, again I did not yet try anything with it. I have a lot of Hg but its toxicity discourages me so I would prefer less toxic ways.

woelen - 19-3-2021 at 03:05

A full 2.5 kg of extra pure copper sulfate pentahydrate.

I intend to revisit copper chemistry in more detail now, with really pure reagents, and make new compounds, and also make all kinds of colorful complexes. I think it is possible to make a whole rainbow of colors with only copper as transition metal. If I have iteresting results, I certainly will make a web page about that.

arkoma - 19-3-2021 at 23:23

10lbs of Potassium Nitrate powder from Walmart of all places. $34US delivered. Be worth a recrystallization, but won't need that for stuff like making Nitric Acid. Go nicely with the bucket of Sulfuric Acid I have.

I'm jealous of you all in the US able to get chems so cheaply. I pay more than that for 1kg of potassium nitrate.

in my country you can buy 25 kg KNO3 food grade for 71 EUR

or less pure (but still 99,8% which is very nice) for 55 EUR

I do not know if you live in the Czech Republic or Slovakia, but I thought there were regulations on similar chemicals in the EU. My country produces a very large amount of ammonium nitrate so it is very cheap it costs 50 kg 50 GEL(15$). I have a bag half full, but I have not used it for a long time.

Only easy way to get pure dry ammonium nitrate where I am at is Tannerite at the ever ubiquitous sporting goods stores.

I think almost every country produces very large amounts of ammonium nitrate. Afaik even my country makes shiploads of it, as it's used everywhere universally as a fertilizer. It's also the only nitrate that is regulated by EU, as well as by stability and as purity for general public, and sale of around over 50% pure AN is prohibited. The limit was 14% by weight of nitrogen if I remember correct, as 34% would be pure. Other nitrates are not regulated, but they are on the suspicious transactions list.

I see that at least potassium and calcium nitrates are readily bought in 25kg bags for about the same price unit, although the suppliers are not walk-in-stores but more like per order, and even when they do sell by bag, they have a checklist for a full pallet of 40 bags on their site. Ironically, ordering a full ton of it would look less suspicious than just one bag. I haven't ordered one, because I definitely don't need 25kg of it, a kilo or two at max over a few years, so keeping a huge bag of the stuff lying around would be stupid.

If you ask me EU regulations are great, the substance is very dangerous, for example the explosion of Beirut. This ammonium nitrate was exported from Georgia to one of the African countries in 2013, but it was stopped in Beirut, and much more was lost than it exploded. I am sure it was scored in one of the Middle Eastern countries (I will not name it). I mean it should not be sold so easily because many countries and certain groups dream about it.

Many countries likely have more advanced methods for producing ordnance, albeit AN is a cheap, bulk material. I'm in it to prevent the bad guys from getting it, but I also fear a lot that I end up on the suspected bad guys' list just because if I purchase certain reagents.

The beirut was just grave lack of safety measures, but on the same time a very classic cause for a disaster: something ends locked up because of some form of bureaucracy or a conflict of interest, and while being on hold, no one has incentive to move it because it'll likely be temporary, but it eventually becomes long-term issue, but the chain of command has already been forgotten and people just live with it. Then, some minor disaster like electric fire spreads a little and initiates a chain of events.

Oh, and my latest order/purchase? Two bottles of ethanol, ready to be stripped clean.

vano - 22-3-2021 at 13:32

Is it possible to be considered a bad guy in your country after purchasing certain compounds?

Luckily I do not have similar problems, probably because no one except me buys similar chemicals here. As for the explosion, I agree, it was just caused by negligence. (Or not, but we will never know)

I moved on a bit from the topic, therefore chemicals which i bought last were lithium hydroxide, sulfamic acid, dichloromethane and just daily acids.

vano - 23-3-2021 at 04:50

Two grams of samarium. I did not think it would have such a ridiculous size, I saw such a small vial for the first time.

arkoma - 30-3-2021 at 13:35

just did a quick and dirty nitrate test on the KNO₃ I got from Walmart online. H₂SO₄ + product from Wallyworld + copper = NO₂ fumes.

Damn good deal at $3.20/lb delivered!

Fery - 1-4-2021 at 11:28

Vano I've bought 1 kg of Sm metal for 130 EUR to explore its usage in organic chemistry (SmI2)

Too much

. I'm sure you will do very good things. Iodide is an excellent reagent in organic chemistry, but I have so little, its use is nonsense.

arkoma - 5-4-2021 at 11:12

Happy to report on the Wallyworld nitrate. Already distilled a half litre of HNO₃

Walmart's online shopping is like Amazon: many of their items are actually sold and shipped by 3rd party sellers, not by Walmart itself. You won't find bags of pure KNO₃ in the physical store (that being said, you might be able to find stump remover which is impure but quite easy to clean up).

Fyndium - 5-4-2021 at 13:17

Damn. Here in Europe they sell products that does not contain anything else but "biologically active enzymes" for your garden, window cleaning, drain opening, etc.

It arrived!! Now to do silver chemistry

I just got some methyl p-salicylate (methyl paraben) from aliexpress. i have a few things in mind for it.

In my area you can buy KNO3 for meat curing even in hardware shop.

i'm thinking about blowing $20 on a bottle of skatole, just to find out what it smells like.

3,4,5 TMBA

woelen - 15-4-2021 at 06:14

Analytical reagent grade basic lead acetate, having approximate composition Pb(OH)_1.15(CH3COO)_0.85. I could obtain 500 grams of this for only GBP 6. It dissolves in water, giving an opalescent white solution. On addition of a little acetic acid, the solution becomes colorless.

Analytical reagent grade sodium tungstate, Na₂WO₄. A sealed bottle of 100 grams for again GBP 6.

I also obtained a few ampoules, each containing 10 ml of BBr₃. I did not yet break one of these ampoules. I still am thinking about what kind of experiments I can do with this extreme reagent. As long as the material is in the thick-walled glass ampoules, I have no storage issue with these.

dawt - 29-4-2021 at 09:39

Got me some TAED, sodium percarbonate and turpentine. Anyone got an idea where this is heading?

Fery - 30-4-2021 at 03:22

Na percarbonate + TAED you can make your white clothes even more white and shining. Distilling turpentine using powerful column and variable reflux ratio distillation head you can separate alfa pinene and other terpenes, depending on the source of turpentine (EU turpentine usually contains most of alfa pinene and less beta pinene). Maybe you can oxidize double bonds of the alfa pinene. Or if you have source of HCl gas you can make an addition of dry HCl gas to alfa pinene to produce bornyl chloride

dawt - 30-4-2021 at 05:58

@Fery: Exactly! My plan after fractionation of the turpentine is to
1. epoxidise the alpha-pinene: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S...
2. rearrange the alpha-pinene epoxide to campholenic aldehyde: https://patents.google.com/patent/US4052341A/
3. do some aldol-condensations with simple aldehydes and ketones, followed by reductions to yield some funky sandalwood smelling compounds. Seems like all of the big fragrance companies have their own patented analogs (under trade names such as Brahmanol, Santaliff, Sandranol, Sandalore, Ebanol etc.) and I'm interested in smelling the differences

There's a decent overview in Surburg, H.; Panten, J. Common Fragrance and Flavor Materials: Preparation, Properties and Uses, 6th ed.; Wiley-VCH Verlag: Weinheim, Germany, 2016.

Courtesy of B(a)P, the absolute legend. If anybody's looking for me I'll be busy oxidising things.

dawt thx for the link, very interesting route available to everyone!!!
also D-limonene from orange peels (or orange oil) could be epoxidized the same way producing limonene oxide:
http://www.thegoodscentscompany.com/data/rw1124781.html
also carvone (s-carvone stereoisomer could be extracted by hydrodistillation of cumin, the other stereoisomer l-carvone I prepared by 3-step synthesis from D-limonene and later I've bought here)
