Moreover, higher water content in the ionic liquid was favorable for obtaining higher enantioselectivity, however it lowered the reaction rate and(DL)-menthol conversion.
另外，在离子液体中，水含量的增加在一定程度上可以增大酯化手性选择性，但反应速率会被降低。
Distilling excessive menthol after reaction, filtering the liquid phase at a high temperature, separating the catalyst, stewing the filtrate for overnight stratification.
反应后蒸馏出多余甲醇，反应液相趁热过滤，分离出催化剂，然后将滤液静置过夜分层。
