How do you convert acetic acid to acetic anhydride?
Acetic anhydride (CH3CO-O-COCH3) can be made from acetic acid (CH3COOH) by treating it with phosphorus pentachloride (PCl5) or dicyclohexylcarbodiimide (DCC).
With PCl5, the reaction is a two step process.How is acetic anhydride produced from acetic acid?
It is known that acetic anhydride can be prepared via the reaction of acetic acid and ketene.
Ketene, a valuable intermediate for the synthesis of many organic compounds, may be prepared by the thermal decomposition (continuous cracking) of acetic acid in the presence of a catalyst, e.g., triethyl phosphate.
