I can't read the one on the bottom left, but some of the labels are really hard to translate, what could "potasio dicromato" be?:D From the looks of it, it looks like 30% H2O2, K2Cr2O7, Na2S2O3, MnSO4, KIO3, and NaNO3 yes?

Looks like some redox titrations going on.

"Mumble mumble pink lid" is actually starch (almidón in spanish). It was my secret weapon but unfortunately I took the picture with few light. Anyways, both of you got 100% in spanish:D

Some special chemicals (this time for experimenting, not for sample collection):
- sodium cacodylate
- arsenic 99+%

Cacodylate (arsenic in oxidation state +5) is much less toxic than cacodyl (arsenic in oxidation state +2) and cacodyl oxide (arsenic in oxidation state +3). I only purchased 10 grams, enough for some simple experiments.

I will be very careful with these chemicals!!

That's what we used as a distillation flask in the old days before the advent of RBFs and ground glassware. I have one but never use it. ;)


I have about 5 of these in varying sizes. They are pretty useful for quick and dirty distilling.

My last order ... well that's been like 2 or 3 months already...

I think it was

- Sodium Cacodylate ( strange that woelen bought the same stuff xD )

- Sodium Boronhydride

- And the main chemical for my research (100g) that I won't really spell out here ^^ .

Here's a great product. Mixed acids from the local farm supply store. It arrived togay (that's togay as I am very gay today).

Got a few gallons of glycerine just in case I run out :P

Jock88, are you going to attempt to separate the nitric and sulfuric acids or just leave as is?
Do you know what proportions it is?

My last Order consisted of some Oxalylchloride, MTBE, Diethylamine, 2-Butylamine, NaBH4 and a few grams of 5-Bromoindole.
So glad i´m not living in the land of freedom!
Next order will consist of more fresh Red-Al, 3-Fluorobenzaldehyd and fumaric acid, i like this stuff, but one needs so much of it (Red-Al, not the fumaric acid :D)...

Chromium Trioxide 500g (Cos it was cheap. Cos I can. Cos there are a bunch of interesting things that I can do with it. Thanks to all who helped answer my questions.)
Ammonium Chloride 500g (Because I don't currently have any ammonium salts)
Potassium Nitrate 3000g (How useful is that? And only marginally more expensive than 500g.)
Sodium Nitrite 500g (Because it is useful to make N2 gas simply and is probably the easiest way for me of getting an inert atmosphere)
Sodium sulfite 500g (Good to have a reducing agent without the limitations of thiosulfate)
Zeolite 3A molecular sieve 500g (always good to have some on hand)


Next up... a round of acids. Followed by some glassware. Followed by some nice element acquisitions -- Na, Ce, Ca, Se
And then I might consider my lab stocked -- at least for now.

It is not only interesting for making N2, but it is amazing to see how many interesting experiments you can do with nitrite. The ion is quite reactive in aqueous solutions, and it allows formation of many complexes, but also formation of organic nitrites is extremely easy.

Some nice experiments with it:
- Making gaseous CH3-O-NO with methanol and some dilute acid and burning the gas (note: flame color is really weird, it is gray). You can also make ethyl nitrite, isopropyl nitrite and higher nitrites very easily.
- Complexes with many metals. Think of copper, cobalt, nickel.
- A very weird reaction with thiocyanate ion in acidic solution.
- As a mild oxidizer, but sometimes also useful as mild reductor.

Thanks woelen.
That grey flame sounds intriguing. (Is it perchance a blue-ish low temperature flame with some soot in it?)
I have a lot to learn about complexes. Looking forward to experimenting.
Thiocyanate is on the to-buy list as well. I will have to play with that.
Always a mine of information. :)

My lab journal tells me that it is well over a month since I last got any decent amount of time doing anything serious. I have much to label, tidy and store properly. I don't know when my next decent time allotment will be. Life is like that. And the more I read here the more little projects I have. All good though. If I can buy what I need then I am ready to go when time becomes available.

Some interesting things since my last post:

Acetic anhydride, 1L - for cellulose acetate, acetyl chloride, aspirin, etc.
Calcium propionate, 500g - eventually to form propionamide and mono- and di-ethylamine
Dextrin, 450g - because making it myself is a pain.
Monosodium glutamate, 225g - I'm curious about the taste, and I can experiment with glutamic acid, alpha-glutaric acid, etc.
CuO, 900g - for CuO/Al thermite
Potassium persulfate, 450g - Myriad of uses from cleaning glass to explosive metal persulfate salts
CaO, 450g - Because roasting CaCO3 is messy and introduces contaminants. Experiments with guanidine and cyanamide.
Potsssium ferrocyanide, 800g - For HCN, NaCN, KCN, and testing for iron.
K2CO3, 2.2kg - For salting out vodka ethanol. Lab video.
NaOAc trihydrate - For a lab video. Made glacial acetic from it.
30 micron Al powder - For thermite, amalgamation, and H2 generation
Benzyl alcohol, 112ml - As a reference sample for benzyl bromide -> benzyl alcohol
Salicylic acid, 500g - Saw it and wanted it. Easier than making it from ASA. Can make ASA from it as a demo. Makes trinitrophenol synth easier and faster.
Sodium bromide, 1kg - Needed it for Br2 and lab video.

Best of all I am now the proud owner of a 500ml round-bottom, single-neck 24/40 fused quartz boiling flask! With my UVC lamp, this opens many excellent possibilities.

I also picked up some various inconsequential bits of glassware - a few multi-neck flasks, stir bars, rods, a dean-stark trap, a short path condenser.

For the curious, anyone can check up on my current stock here, a link that is also located in my signature.

I would love to get a fused quartz boiling flask! Amazon.com has them but not .ca. I hate Canadian amazon :mad:

You can use UV light to chlorinate toluene, chloroform, dimethyl carbonate, etc to make all kinds of interesting things.

Is it safe to use a quartz flask with a regular condenser for reflux?

Two very rare and hard to obtain chemicals:

Tl2O3
TiO

Both of them allow aqueous chemistry with elements in unusual oxidation states and thallium is hard to obtain and rare anyway.

Thallium! Very interested in what you get up to with that. Thallium cacodylate?? Or perhaps complete hair loss is trendy over there? Good luck with whatever is planned

Exactly! I plan to make benzyl alcohol from toluene/bromine/NaOH, as a start. I can use it to make benzotrichloiride, which can be used to make acid chlorides and thionyl chloride. Lastly, exhaustive free radical chlorination of methyl formate gives trichloromethyl chloroformate, or diphosgene, a convinient source of phosgene in the lab. It can convert amines into isocyanates, secondary amines into carbamoyl chlorides, carboxylic acids into acid chlorides, formamides into isocyanides, etc.

I have a 254nm UVC germicidal lamp that will be employed for these tasks.

I am still looking into the reflux condenser compatibility. I think I will use teflon tape as padding in the joint to help with potential thermal expansion issues.

woelen - That's impressive. Your thallium scares me. At least phosgene toxicity is not cumulative. :)
