Open publisher page 0 citations

Abstract

Phospho-tungstic heteropoly(H3PW12O40) was prepared and its catalytic performance for synthesizing of ethyl hexanoate from hexanoic acid and ethyl alcohol were studied.The results indicated that H3PW12O40 was a good catalyst for synthesizing ethyl hexanoate.the optimized condition was as follows: the molar ratio of hexanoic acid to ethyl alcohol was 1∶2.0;the weight of hexanoic acid was 0.5 g/0.1 mol;the water-carrying toluene volume was 8 mL;the reaction time was 150 min;the yield was about 97.2%.
