Abstract

The features of the liquid-phase hydrogenolysis of glycerol to 1,2-propylene glycol over Cu/Al₂O₃ catalysts (Cu = 2–80 wt %) and individual copper particles have been studied. It has been shown that the main factor determining the activity of the catalysts is the specific surface area of copper. It has been found that the Cu/Al₂O₃ catalyst containing 60 wt % Cu is the most efficient. A new reaction mechanism is proposed based on the obtained data.

甘油液相加氢水解中的含铜催化剂

摘要

研究了在Cu / Al ₂ O ₃催化剂（Cu = 2–80 wt％）和单个铜颗粒上甘油液相氢解为1,2-丙二醇的特性。已经表明，决定催化剂活性的主要因素是铜的比表面积。已经发现，包含60wt％Cu的Cu / Al ₂ O ₃催化剂是最有效的。根据获得的数据，提出了一种新的反应机理。
