Acetophenone


I've tried looking up MSDS for products containing acetophenone but most either have the minor product as acetophenone, 100% acetophenone, or a mixture of acetophenone and another ketone (would be hard to separate.

Firstly, is acetophenone any kind of precursor chemical? I just need it as a solvent and don't want any feds showing up at my door. I know benzaldehyde is a no-no, but acetophenone I would assume is a green light.

But if it isn't, does anyone have any insight in the acquisition of it, or synthesis?

I can't think of any compounds off the top of my head that would create an easy otc synthesis of this stuff. Acid chloride/fecl3 + benzene = haha no thanks.

I'm not sure what your criteria for "easy" are, but it can be prepared by pyrolysis of a mixture of calcium acetate and benzoate. It doesn't require any exotic or expensive chemicals or apparatus, but it is high temperature. I wouldn't worry about buying it (but making it would be more fun and educational :P). If you are using at a solvent you may need more than you can conveniently synthesize.

Acetophenone is perfectly legal to own and/or purchase.

there are also a few ways to make it from styrene monomer. I am sure there is a thread about acetophenone synthesis if you search the forum (use google).

The joys of acetophenone


Acetophenone is not restricted as to sale or possession nor is it listed as a "watched" chemical as far as I'm aware. In fact, I purchased a mostly-full bottle of this reagent two or three years ago on eBay, and so far no early-morning federal ninja raids (knock on wood!).

Because acetophenone is one of those substances having a melting point right around room temperature, it's fun to hold the bottle and slosh it around as it turns from solid to an icy slush from the heat of your hand (I'm rather easily amused, it seems). Plus I'm quite keen on the scent of it--it smells sweetish, like a cross between acetone and benzaldehyde as might be expected, but rather cleaner or crisper than either of those.

NOT TRUE!


depending on what country you are in. A canadian chemist recently ordered some from a chem co with whom she has years of history only to be informed that,

"That's a restricted item, Acetophenone is now a schedule VI, class A precurser. To order it would require filling out an end use declaration . . ."

They are mistaken. She should get them to re-check it

Not so sure about that, Ab2 saw the EUD form with a Health Canada logo on top. She said it was emailed over in less time than it would take to prepare it. It clearly stated Acetopheone was Class A precurser on Schedule VI.

And this was from a Chem co that doesn't bat an eyelash when N,N-Diisopropylethylamine is ordered.

Oddly enough there is no mention of this on the RCMP, Justice Canada, or Health Canada site. In fact the last time those lists were updated is 10 years ago. So it is obvious that the chem co's are working from a different list than what is made public.

@symboom - very nice site! Thank you.

Hmm that's interesting!

Ive heard rumors of new restrictions recently from suppliers. Of course they don't know exactly what it is, they just order it from the big company. Why wouldn't new laws be on the website? Isn't that the point of law?

Maybe they mixed it up with phenylacetone. benzyl methyl ketone vs phenyl methyl ketone.

Ab2 assumed it was because it was a precurser to Phenyl acetic acid, but could be wrong

Yep phenylacetic acid can be made from acetophenone one pot trough the willgerodt reaction, but hell one can use instead plain styrene!

Sure it's a mistake, may be as said they messed acetophenone with P2P. Any ways, are in canada precursors to PPA controlled? As in the US benzyl chloride and benzyl cyanide are highly watched. For example in my country, benzyl chloride and benzyl cyanide are watched but unofficialy, there are some kind of end use sheets but you can get the products from a chem supplyer without questions, since no one knows that sheets exist and if ppl want amps they go to Holland or eastern europe. They ain't smart enough to make their own P2P from PAA, let alone making their own PAA...

So if more obious PAA precursors like benzyl cyanide aren't watched in Canada, it's a safe assumption that the company messed with the chemical names.

Acetophenone is on list V part I (hmm VI?) of the approved livestock food additive list.

http://www.inspection.gc.ca/english/anima/feebet/ind/sched/s...

Any and all bills which affected the drug precursor list died when the house was dissolved (I only know of Bill S-10 which made no mention of Acetonphenone) and as the house has not yet had its first sitting, no new changes to the Drug act could have been made.

Yeah and Phenyl acetamine is only a simple hydrolysis away from PAA, witch can be done one pot (at least in the morpholine variation) I think you should know.
