摘要：

The catalytic performance of acidic ionic liquids (ILs) was evaluated for the hydrolysis of cyclohexyl acetate to cyclohexanol. Cyclohexyl acetate conversion increased with increasing acid strength of the ILs, but the five SO3H-functionalized ILs with different acidity had similarly high activity. All of the ILs exhibited high selectivity to cyclohexanol. This can be attributed to the high polarity of the ILs, which inhibits the formation of the transition state for the side reaction, pyrolysis of cyclohexyl acetate to cyclohexene, and then increases cyclohexanol selectivity. Under optimized conditions, cyclohexyl acetate conversion was 80.2 with 96.6 % cyclohexanol selectivity over [HSO(3)bmim]HSO4 (bmim = butyl-3-methyl-imidazolium). Moreover, [HSO(3)bmim]HSO4 also showed high reusability.
