气相加氢是草酸二甲酯特有的一种性质,具有高层级的活性特性。采用共沉淀法,可以制备出具有不同规格的沉淀剂。特性乙二醇的合成,会受到各种条件的影响,比如:组合范畴内的催化剂、拟定好的反应条件等等。为了表征所制备得到的催化剂特性,需要通过一些特定的流程,包括:吸附流程、脱附流程。通过查验,我们得出的数值表征了草酸二甲酯特有的加氢反应,这与铜离子的活性状态密切相关。如果能在原有的表面积上进一步扩展,则能增强其活性。通过气相催化制备出的乙二醇,草酸二甲酯具有极高的转化率,能够达到97%以上;乙二醇的选择特性,也能达到85%左右;并且制备得到的催化剂,具有明显的最优稳定性。
Gas phase hydrogenation is a unique nature of dimethyl oxalate, with high levels of activity. Using coprecipitation method, can be prepared with different specifications precipitant. Characteristics The synthesis of ethylene glycol can be affected by various conditions, such as the catalyst within the combined range, the well-defined reaction conditions, and the like. In order to characterize the prepared catalyst properties, we need to go through a number of specific processes, including: adsorption process, desorption process. Through testing, we obtained the value of the unique hydrogenation of dimethyl oxalate reaction, which is closely related to the activity of copper ions. If you can in the original surface area to further expand, you can enhance its activity. Glycol prepared by gas-phase catalytic, dimethyl oxalate with an extremely high conversion rate, can reach more than 97%; ethylene glycol selectivity, but also can reach about 85%; and the prepared catalyst has obvious Optimal stability.
