| Abstract: | The esterification of acetic acid and lower alcohol was studied by using the catalyst of rare earth solid superacid. Results showed ternary rare earth solid superacid S202-8/Nd2O3-ZrO2-A1203 possessed the highest catalytic activity. Other optimum conditions were as follows ： Ratio of acid to alcohol of 1 ： 2, catalyst amount of 0.75 g, acetic acid amount of 0. lmol, reaction time of 3 h. Under these optimum conditions, the esterification efficiency can reach 96.16% ,the esterification efficiency can still be over 92% when the catalyst is reused within three times. |
