Abstract

Ethyl acetate was synthesized at the use of the catalyst aluminium chloride with acetic acid and ethanol,and related factors were studied.The results showed that aluminium chloride was 9%(acetic acid) the acetic acid-alcohol ratio was 1.5∶ 1,the pre-reaction was 12 min,the total reaction time was 1.5 h,the reaction temperature was 90~95 ℃,the yield of product could reach 74.1%.The craft was clean production,the refractive index(nD20) of ethyl acetate was 1.372 1,the fruit flavor product was colorless and transparent.
