FIELD: industrial organic synthesis. SUBSTANCE: high-quality alkyl acetates are prepared via reaction-rectification- mode esterification of acetic anhydride with corresponding alcohols. Reaction is conducted on reaction-rectification column enhancing relative volatility of alkyl acetates at equimolar ratio of reactants at 50-100 C and pressure 1 atm, reaction time being 0.5 to 3.5 h. EFFECT: reduced power consumption in product isolation stage and increased purity of final product. 2 dwg, 3 ex
