介绍了碳酸二甲酯酯交换合成碳酸二乙酯两步反应的多种多相催化剂的筛选试验结果。在测试之前，催化剂被激活。在沸石的情况下，脱铝只会导致活性的轻微增加。对于活性最高的催化剂，确定了反应精馏塔建模和过程模拟所需的动力学参数。分析了在反应精馏塔中发生酯交换反应的过程，将最好的催化剂作为规整填料的一个单元。(C)2006爱思唯尔B.V.保留所有权利。
Results of screening tests are presented concerning a number of heterogeneous catalysts for the two-stage reaction of transesterification of dimethyl carbonate to diethyl carbonate. The tests were preceded by the activation of the catalysts. In the case of zeolites, dealumination led to an only slight increase in activity. For the most active catalysts kinetic parameters were determined necessary for the modelling of reactive distillation columns and process simulation. The process was analysed in which the transesterification reaction occurs in a reactive distillation column, with the best catalyst incorporated as an element of the structured packing.
