| Abstract：SO 2- 4 MoO 3 TiO 2 was prepared and it was used as catalyst in esterification of adipic acid and ethyl alcohol. The conditions of the esterification were discussed. In the optimum condition, the yield of diethyl adipate was 97%. The optimum condition was as follows: adipic acid 0.1mol, ethyl alcohol 0.6mol, the catalyst 1.2g, cyclohexane 15ml, reflux for 4h. |
| Key words：SO 2- 4 MoO 3 TiO 2; diethyl adipate; catalytic esterification; |
