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。
Its advantages include high activity and selectivity of catalyst, easy separating and reuse of catalyst, and low cost.
且催化剂颗粒较大，易于从反应产物中分离，催化剂可重复使用，明显降低了生产成本。
The result and some important experimental conditions such as the catalyst and water separating agent were studied.
此外对实验结果及反应所用催化剂、分水剂等做了讨论。
