As in anhydrous acetic acid? Or acetic anhydride?
GJ, do you know a way of using anhydrous acetic acid in that sort of procedure? (ie glacial acetic acid?) I'd love to hear some details, I've only heard of acetic anhydride and acetyl chloride being used for that purpose.
HoH, I'd hang onto it. Who knows, your direction may change in the future... GAA is a handy chemical to have around.
