摘 要:<正> The catalytic activities of TiSiW12O40/TiO2 in synthesizing ethyl ester, propyl ester, n-butyl ester, and amyl ester were reported. It was demonstrated that TiSiW12O40/TiO2 is an excellent catalyst. Various factors concerned with esterifica-tion were investigated. The optimum conditions were found: the mole ratio of alcohol to acid is 1.3:1, the mass ratio of catalyst to reactants is 1.5%, and the reaction time is 1.0 h. Under the optimum conditions, the yields are 88.0% for ethyl ester, 94.5% for propyl ester, 98.6% for n-butyl ester, 99.1 % for n-amyl ester, and 96.7% for iso-amyl ester, respectively.
