Abstract:

A mild and efficient method for diacetylation reaction was developed, by which diacetate could be achie- ved through the reaction of aldehyde with acetic anhydride, in the presence of cobalt sulfate, with an admirable yield, at room temperature, without solvent. The catalyst could be recycled six times without a distinct loss of activity.

Key words: Diacetate; Aldehyde; Acetic anhydride; Cobalt sulfate
