固体超强酸SO_4^(2-)-MoO_3-TiO_2催化合成己二酸二乙酯

Synthesis of Diethyl Adipate by Using SO_4^(2-)-MoO_3-TiO_2 as Catalyst

制备了新型催化剂SO2 - 4 MoO3 TiO2 ,考察了该催化剂在己二酸二乙酯合成反应中的催化活性 ,优化条件下 ,己二酸二乙酯的收率达 97%。优化条件如下 :己二酸 0 .1mol,无水乙醇 0 .6mol,催化剂 1.2g ,带水剂环己烷 15ml,回流温度下反应 4h。

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.
