草酸二甲酯气相催化加氢合成乙二醇探讨

Study on hydrogenation of dimethyl oxalate to ethylene glycol

采用共沉淀法进行草酸二甲酯加氢催化剂的制备,利用这种方式制备相关的沉淀剂有着不同特性的规格。为此在一定的组合范畴之内,在试验中所使用的催化剂、所拟定好的一定的反应条件,这些问题都会在合成过程中对乙二醇的特性产生一定的影响,并且更好的去凸显其本身的性能和影响。

The preparation of dimethyl oxalate hydrogenation catalyst was carried out by coprecipitation method, which was used to prepare the related precipitant with different specifications. For this reason, within a certain range of combination, the catalyst used in the experiment and the prepared reaction conditions, these problems will have a certain impact on the properties of ethylene glycol in the synthesis process, and better highligllt its own performance and influence.
