Edit, so excited I got the mass wrong

I cam across some so-called "new old stock" chemicals. Material, which is old, never used, and still in unopened original package. Some chemicals, which you normally cannot find easily:

sodium arsenate
methylamine HCl
phenolphtaleine powder
sodium chloroacetate
urea (analytical grade, not the greasy prills you normally can buy as fertilizer)

Best thing is the very low price for these chemicals.
The methylamine HCl can be useful for making methylamine easily. Just mixing with NaOH and gently heating drives off the gas and allows me to do experiments with that. No problem where I live, methylamine is not forbidden in NL.

Choline chloride and glycerin for extracting alcohols from crude esters. https://www.sciencedirect.com/science/article/pii/S004040391...

Holy Sh*t, I wouldn't touch sodium arsenate with a 60 foot pole!

Here in Poland I have one very good seller that I order usually from. He has small company offering small quantities of reagents in low price for experiments. One can as well order bigger quantities with discount. This company has wide choice of reagents and what's funny about it, that the reagents are packed in urine containers, some in milk bottles and some in cheap plastic or glass bottles. It looks very oldschool and has its climate and although it is packed in such way, the reagents are good grade. The seller is also very communicative.

Lately I ordered from him anhydrous AlCl3, which was little above 2 times cheaper than normally in Poland and i'm very pleased with the order.

Unfortunately I'll have to wait. The seller's postal service does not ship abroad anymore, due to the Covid-19 crisis. The seller will check out at regular intervals, but till that time he cannot ship the materials. I ordered some other stuff at the same seller in February and that order still could be shipped, but now I'll have to wait for an unknown period of time :(

Nothing particularly special. But I have been so inactive of late every little thing is noteworthy.

I ordered a kg of Al powder from auschems. I found a couple of other items already stored in my basket from waay back: some ammonium carbonate and benzoic acid. No immediate plans but good to have some basics. Now, if only they had some zinc powder in stock. I am nearly out.

Of course I wishlisted a bunch of other items that I have no need for but will probably get when I have spare cash.

Arrived within 4 days. Auschems is pretty darned good.

This is "DPD 1" pills for pools. I believe it is N,N-Diethyl-p-phenylenediamine and I need it for the purpose of quantitative chlorine analysis in gas experiments.
I am not sure whether is it a pure compound or some mix, but it is easily available, so I will try.

Got some calcium bromide CaBr2.xH2O yesterday. For making metal bromide salts by double displacement with the metal sulphates. I wanted 100g but the supplier only had 500g bottles available so if anyone in my area wants to buy some off me just message me....

I was wondering what was in these but had not got around to looking it up.

The cheapest I have seen them is $0.12 per pill which is good enough for intended use but not a great price for bulk. But if you are using it as an indicator, you might not need too much.

Do start a thread to let us know how your experiment goes. I am sure I am not the only one interested.

Today I received fine nickel powder (100g) and food grade calcium acetate (200g). Nickel powder to try and make nickel iodide one day, and the calcium acetate to give me a route to make metal acetates by double displacement of metal sulphates with the calcium acetate.
Also ordered sodium molybdate on eBay, as price seemed to good to pass on. But not arrived yet.

My order for a 1/4in stainless steel needle valve arrived today. It cost £5.30 including postage from China. The quality looked reasonable and it looks like it has a PTFE ring for sealing the stem. On close inspection of the needle its not seating uniformly and when tested in the closed position it leaks slightly.

I see the price has gone up by about £1




i am wg48 but not on my usual pc hence the temp handle.

Thank goodness for Fleming and the fungi.

Not directly an order, as it was a gift from a friend, but I got some nice treats I looked around to acquire instead of isolating them myself.
Actually only wanted the natural allybenzene for my planned synthesis route, but well, now I got some isomerized propenylbenzene of that substance as well :)
I'm talking about apiole and isoapiole, just a few grams each but thats enough for my plans.

With the allylbenzene I plan to brominate it, and then go on to prove the simplest primary amination method to work as expected on that substrate.
A tiny little revolution one could say, since this replaces the use of either benzylamine followed by CTH debenzylation, or the use of NaN3 followed by reduction to get the primary amine.
No, I will use a cheap, harmless, well working, and very mild method, I will use sodium diformylamide!
I love that gabriel reagent, it is the best really!

I just bought 64 oz of Liquid Lightning at WalMart. https://www.walmart.com/ip/Liquid-Lightning-Virgin-Sulfuric-...

Crystal clear color, density was measured as 1.818 g/ml @ 27 C which corresponds to 92-93% w/w. Make sure you buy the white bottle shown in my link, which is the virgin/unbuffered formula marketed to professionals. The black bottle is impure garbage, dark brown in appearance with buffers and a concentration (per the MSDS) of something like 44% w/w.

A couple of kg of zinc ordered off ebay which I intend to make into powder.

Nothing remarkable in that but the seller, Toby from gembrookcreek recognised me from this board. I am not used to being recognised. Anyway, we had a pleasant little interchange via ebay.
FTR, gembookcreek has a few different metals for sale at what seem to be reasonable prices.

How do you plan on making the zinc into a powder? Sounds interesting but also sounds like a lot of work.

Electrolysis in alkaline solution. Nurdrage has a video on this. He dissolves Zn in NaOH solution and electrolyses with Cu cathide and inert anode. The fine zinc falls off the copper. I intend to use Zn anode so that the zinc in solution is self replenishing.

The material could be shipped, the Covid-19 regulations were loosened. The parcel arrived. I have done my first experiment with the arsenate ion, in comparison with phosphate ion.
