subtitute acetic anhydride

[pziko]

i do not have acetic anydride in my reach and want to do this reacytion

 

50 g phenylacetic acid, 25 g anhydrous sodium acetate and 850 ml acetic anhydride are refluxed with stirring under moisture protection for 40 h.

 

wich produces phenylacetone.

 

so wat other solvent is best to use, instead of acetic anydride.

If someone used acetic anhydride they probably needed it.

 

What do you want phenylacetone for (and why do you think it's difficult to get acetic anhydride)?

Do you have ketene?

 

H₂C=C=O + CH₃COOH -> (CH₃CO)₂O

The acetic anhydride isn't just a solvent in this case. It's rare that it would be there as a solvent only.

 

I would also like to echo John Cuthber's question, though. What do you need to make a schedule II controlled substance for, or is it really as obvious as it seems?

[John Cuthber]

Lets face it, anyone with a legitimate need for P2P can buy it (or buy acetic anhydride).
