考察了不同溶剂中Pt/WO3/ZrO2催化剂催化甘油加氢制1,3-丙二醇的反应性能.结果表明,质子溶剂乙醇和水有利于甘油转化为1,3-丙二醇.含有乙醇或水的二元混合溶剂表现出明显的溶剂组分协同效应,使用混合溶剂时1,3-丙二醇选择性超过使用单一溶剂,而且混合溶剂的组成对反应性能影响很大.
Different solvents were studied for dehydroxylation of glycerol to1,3-propanediol over a Pt/WO3/ZrO2 catalyst. Protic solvents such as ethanol and water favored the formation of 1,3-propanediol from glycerol. Binary solvents containing a protic component showed a synergetic solvent effect on the selective dehydroxylation of glycerol to 1,3-propanediol. The protic component in the binary solvent influenced the performance of the Pt/WO3/ZrO2 catalyst.
