草酸二乙酯气相催化加氢合成乙二醇的研究

摘要对草酸二乙酯气相催化加氢生成乙二醇反应进行了实验研究。研制了不含铬的铜基催化剂,并考察了催化剂的制备条件对反应结果的影响。结果表明,Cu/SiO_2质量比为0.67,活化温度为350℃时最佳。在上述催化剂制备的基础上,提出了最佳反应条件。

Abstract： In this thesis,Catalytic hydrogenation of the diethyl oxalate to ethyle-ne glycol was studied.The catalysts of copper without chromium was stu-died.The effect of preparation condition of the catalysts on the reactionresult was experimented.We have found that the preferble Cu/SiO_2 weig-ht ratio of the catalyst was 0.67:1,and the preferable reduction temperatu-re was 350℃.Based on the catalysts,the most preferable reaction condit-ions were proposed.

Keywords： hydrogenation;;ethylene glycol;;diethyl oxalate
