活性炭吸附PMo_(12)催化合成乙酸环己酯

Catalytic Synthesis of Cyclohexyl Acetate Using PMo_(12) Adsorbed on Active Carbon

本实验以乙酸和环己醇为原料,用活性炭吸附12-磷钼酸作催化剂合成了乙酸环己酯,探讨了醇酸摩尔比、催化剂用量、反应时间、带水剂用量对酯化产率的影响,考察了催化剂重复使用效果,确定了最佳实验条件.

This paper synthesizes cyclohexyl acetate using acetic acid and cyclohexanol as reactants and 12-phosphomolybdic acid adsorbed on active carbon as catalyst. The yield of the ester with different alcohol acid molar ratio, amount of catalyst, reaction time,amount of azeotrope agent is discussed,also discussed effectiveness with repeatedly using of the catalyst,and determined the optimized condition.
