摘要

研究了KNO3/HMS对碳酸二甲酯（DMC）与月桂醇酯交换反应制备碳酸二月桂酯（DDC）的催化性能。用XRD、FTIR对KNO3/HMS催化剂进行了表征，采用Hammett指示剂-苯甲酸法测定了催化剂碱强度和碱量分布的情况，并考察了KNO3负载量、焙烧温度以及反应条件对KNO3/HMS催化剂性能的影响。研究表明，KNO3负载后载体HMS仍保持良好的孔结构，KNO3的最佳负载量为13%（质量分数），催化剂的总碱量也在此时达到最高，最佳焙烧温度为600℃;在反应物DMC/月桂醇摩尔比为1∶4、DMC的滴加温度为140℃、反应时间为5 h、催化剂用量为反应物总质量的1%条件下，催化剂的效果最佳，DDC的收率和选择性分别为81.9%和99.5%。

Abstract

The catalytic activity of KNO3/HMS for the synthesis of didodecyl carbonate (DDC) by transesterification from dimethyl carbonate (DMC) and dodecanol were studied.The KNO3/HMS catalysts were characterized with XRD and FTIR.The method of Hammett indicator-benzene carboxylic acid was used to characterize the basicity strength and the basicity amount distribution.The effects of loading quantity of KNO3

calcination temperature and reaction conditions were investigated.The results indicated that the structures of HMS were well maintained

the optimized KNO3 loading amount and calcination temperature were 13%（mass）

and 600℃ respectively.The basicity amount of KNO3/HMS was greatly affected by the loading amount and calcination temperature.At the molar ratio of DMC to dodecanol 1∶4

DMC addition temperature 140℃

reaction time 5 h and catalyst content 1% of the reactants mass

the yield and the selectivity of DDC were 81.9% and 99.5% respectively.
