Excess anhydrous acetic acid


Greetings, ScienceMadness! I have an excess of glacial acetic acid I've synthesized/fractionated that I would be willing to sell to anybody interested. The transaction would go through eBay (I have already been approved to sell acetic acid on eBay specifically), so no worries in that area. As far as costs go, just post or PM what you would like to pay, and quantity. Also, if you need a small amount, I would be happy to send it just for the price of the glass bottle and shipping.

One additional thing, if anybody needs other uncontrolled chemicals, I have worked as a organic/biological chemist over the course of many years, and would be more than happy to synthesize and send them to you, as long as it's for a legitimate, legal usage (of course). Thank you, and I look forward to communicating with all of you!

Title is somewhat misleading as anhydrous acetic isn't glacial acetic acid. Other than that I'm sure someone will find this helpful.

anhydrous AA is very difficult to buy, it consists of 2 AA molecules that have bonded together by losing water. GAA is just acetic acid that has no water in it
http://en.wikipedia.org/wiki/Acetic_acid ''glacial'' comes from the high MP
http://en.wikipedia.org/wiki/Acetic_anhydride

<strong>TMCG</strong>, we're usually a little wary of dealing with newcomers. Perhaps you'd care to introduce yourself a little bit more? At least tell us what area you're from, so we know where you'll be able to ship.

And that of course is the definition of anhydrous. He never claimed to have the anhydride. Even the wiki article for glacial acetic acid that you linked to describes it as:

Quote:
Glacial acetic acid is a trivial name for water-free (anhydrous) acetic acid.


So I see no issue with the description, it is only someone who is unaware of the intricacies of nomenclature that would be caught unaware.

Its not confusing at all, at least not to those skilled in the art.

My question is, how is he making it? Maybe he has a mini-Monsanto plant, or uses a ketene generator.

The issue I have with people selling reagents, is are they determining concentration/purity, and how.

Yes, apologies to anybody who was confused. I believe you understand what I mean now. Just to assure you, I intended "glacial acetic acid" (C2H4O2), not acetic anhydride. If anybody needs more clarifications, don't hesitate!

Absolutely. Well, as I said, I'm an organic and biological chemist. While it is a job, it is a passion (if not greater than a passion) for me; it never ceases to amaze me. As far as personal information, I'm an east coaster, near Washington, D.C. I will ship anywhere UPS allows it to be shipped. (so definitely all of the US, as far as other countries go, it just depends, of course)

Did you notice that one of those compounds is not called acetic acid?
Acetic acid (even if it is anhydrous) is not the same as acetic anhydride.

That sounds great, <strong>TMCG</strong>. Thanks for the introduction.

As far as anhydrous acetic acid goes, anyone who confuses it with acetic anhydride is just <em>being</em> an idiot. Learn your nomenclature, it's really not that difficult. <em>Glacial</em> acetic acid is an antiquated term and/or a colloquialism. Anhydrous acetic acid is unambiguous.

[Don't be offended. Everyone has their idiot moments. I'm not implying that you're always an idiot.]

[edit] <strong>Pyro</strong>, however; you are just wrong.

How are you synthesising it?

Is anybody interested in any chemicals for this part as well?

Also, thank you all for the kind welcoming, and exposing me to a little [good] taste of Sciencemadness.

Apologies for that! I did type a respond but accidentally posted without it. To duly answer your question, I synthesized it using a basic catalytic carbonylation of methanol.

Can you provide some details on the analysis? How was purity determined?
