Synthesis of ethyl methyl carbonate via transesterification over molecular sieves and ZIF-8

摘要：

　　An efficient catalyst system of molecular sieves and ZIF-8 was developed for preparing ethyl methyl carbonate from dimethyl carbonate and diethyl carbonate under mild conditions.We used a number of tools to characterize ZIF-8,including X-ray diffraction instrument and physical adsorption instrument and thermogravimetric analyzer.Chemisorption instrument was used to characterize its acid-base properties.We studied different factors associated with the yield.The catalyst leaching test showed that the reaction took place heterogeneously.The results indicated that the catalyst system of molecular sieves and ZIF-8 displayed excellent activity,selectivity and reusability.Furthermore,the addition of molecular sieves to ZIF-8 resulted in dramatic increases from 50.3%to 84.7%in the yield.
