  Mg–Al hydrotalcites were prepared by the forward, reverse and simultaneous titration coprecipitation methods, respectively. The effects of coprecipitation method on Mg–Al hydrotalcite properties were investigated. The resulting catalysts were evaluated for their performance in the synthesis of diethylene glycol di-(methyl carbonate). The results showed that there were no other crystalline phases, but

  Mg-Al水滑石分别通过正向，反向和同时滴定共沉淀法制备。研究了共沉淀方法对镁铝水滑石性能的影响。评价所得催化剂在二甘醇二-（碳酸甲酯）的合成中的性能。结果表明，没有其他结晶相，但同时滴定法制备的任何样品和高温超导中的Mg-Al水滑石结构均具有最佳结晶度。只有通过正滴定和同时滴定共沉淀法制备的Mg-Al水滑石的Mg / Al比值与盐溶液相似。共沉淀法影响孔结构，镁铝水滑石的比表面积和碱度分布，从而影响其催化性能。HTS具有相对较小的孔径，适中的比表面积和可观的碱度，在优化的条件下显示出优异的催化性能（91.6％的收率）。该催化剂可以容易地分离和再利用。其活性没有明显降低，并且目标产物的产率在5个循环后保持在90％左右。
