Full TextAbstract
Heteropolyacids (HPAs) have been used as catalysts for the reaction of salicylic acid with acetic anhydride. The performance of different forms of heteropoly acids in the presence of acetic anhydride as acetylating agent for acetylation of salicylic acid was compared. The best conditions were observed using Preyssler and NanoPreyssler as catalysts. The catalyst is recyclable and reusable.
