Beschreibung
Zusammenfassung:	A catalyst for synthesizing ethyl ethoxyacetate through hydrogenation of diethyl oxalate is prepared from, by mass, 2.0-65.0wt% of CuO serving as a main active component and 3.5-98.0wt% of Al2O3 serving as a carrier. The catalyst for synthesizing ethyl ethoxyacetate through hydrogenation of diethyl oxalate has the advantages of being high in selectivity, good in stability and suitable for industrial production. 种草酸二乙酯加氢合成乙氧基乙酸乙酯的催化剂是以氧化铜为主活性组分，AlO为载体，催化剂质量比组成为：CuO的含量为2.0~65.0 wt%，AlO为35.0-98.0 wt%。本发明具有选择性高，稳定性好，适用于工业化生产的优点。
