| Abstract: | The synthesis of butyl lactate by using TiSiW 12 O 40 /TiO 2 as catalyst has been studied. The suitable conditions of the synthesis have been investigated, such as the time of reaction, the ratio of acid to alcohol, the amount of catalyst and the effects of the activated temperature to the esterification rate. The experiment results showed that the heteropoly acids salts possess high catalytic activity and special selectivity and the esterification rate of butyl lactate was 92.7 percent. |
