Hey y'all. I have decided to sell my bottle of PCl5 as I no longer need it and it is quite a pain to keep in storage. There is about 250g remaining
(estimating) and it still reacts quite violently with ethanol and fumes profusely in air so most of it is still viable. It has been stored under
nitrogen for the majority of the time I have had it. I would like $110 for it (that includes shipping) and I will ship it to anywhere within the US.
If you're interested, please message me. I will consider all offers including trades for the item or trades for a large discount.
Things I would consider trading it for:
- Centrifuge or Microcentrifuge (doesnt need to be perfect, but must be fully functional)
- Oxalyl Chloride
- Phenylacetonitrile
- Other hard to get or obscure chemicals

If you want oxalyl chloride, you could just use the PCl5 to prepare it from oxalic acid?

That hardly works. Instead the main reaction is formation of CO and CO2, plus POCl3, HCl and some H3PO4.

I suspect this works because of the intermediate formation of a 5-membered ring (-C-O-P-O-C-), but I could be way off.

Well, these folks claim a yield of about 50%.
Not great, but not the worst either.

The problem is; it takes a lot of PCl5 to make a fairly small amount of Oxalyl Chloride. Grams in, versus Grams out, equals a fairly unappetizing
equation.
PCl5 is hard to acquire these days. Unlike past eras, when such items were relatively inexpensive and widely available.

I have a micro centrifuge. PM sent
