摘要

根据目标反应C6H12O6 + 4H2 = 2C3H8O2 + 2H2O，在流动模式下，研究了10%葡萄糖水溶液在负载型含铜氧化物上氢解成丙二醇。结果表明，在负载1.6 mmol C6H12O6/（gcat·h）时，在180℃、4.0 MPa H2条件下，23Cu-1Cr2O3/Al2O3催化剂的丙二醇产率为0.9 mmol C3H8O2/（gcat·h）。发现乙二醇、羟基丙酮、赤藓糖醇、甘油、1,2-丁二醇、1,2,4-丁三醇和山梨醇是该反应的副产物。

Hydrogenolysis of Glucose in Aqueous Solution into Propylene Glycol on Copper-Containing Catalysts

Hydrogenolysis of 10% aqueous solution of glucose into propylene glycol on supported Cu-containing oxides has been studied according to target reaction C₆H₁₂O₆ + 4H₂ = 2C₃H₈O₂ + 2H₂O in a flow mode. It is shown that the best propylene glycol productivity (0.9 mmol C₃H₈O₂/(g_cat·h)) achieves on 23Cu-1Cr₂O₃/Al₂O₃ catalyst at 180°C, 4.0 MPa H₂ under a catalyst load of 1.6 mmol C₆H₁₂O₆/(g_cat·h). Is is found that ethylene glycol, hydroxyacetone, erythritol, glycerol, 1,2-butanediol, 1,2,4-butanetriol, and sorbitol are side products of the reaction.
