【Abstract】 Ethyl caproate was synthesized in the catalysis of H 3PW 12 O 40 by hexanoic acid and alcohol. The affection of the amount of catalysis, reaction time, the ratio of hexanoic acid and alcohol was discussed. The best reaction condition was selected and repeated. The best conversion is over 95%.更多还原
