甘油是产量巨大的生物质.将之转化为有用化合物的研究,有重要的工业应用价值.甘油的氢解可生成一系列的C-3醇,如正丙醇、异丙醇、1,2-丙二醇以及1,3-丙二醇等.其中,1,3-丙二醇是合成聚对苯二甲酸丙二醇酯(PPT)的重要有机中间体.因此,选择性氢解甘油合成1,3-丙二醇,是一个重要的研究课题.最近,在研究Pt/WO3/ZrO2催化下的甘油氢解反应时发现,通过调控催化剂载体中氧化钨含量,可以调节催化剂的酸碱度,从而在保持较高1,3-丙二醇选择性的同时,显著提高反应的转化率.这一技术提高了合成效率,有潜在的工业应用价值.

Glycerol is an abundantly generated biomass and conversion of this compound into useful chemicals is of significant industrial value. Hydrogenolysis of glycerol produces a series of C-3 alcohols, such as 1-propanol, 2-propanol, 1,2-pro-panediol and 1,3-propanediol (1,3-PDO). Among these compounds, 1,3-PDO is an important organic intermediate to synthesize poly-trimethylene-terephthalate. Therefore, synthesis of 1,3-PDO through the selective hydrogenolysis of glycerol is a promising subject. Recently, during our investigations on the Pt/WO3/ZrO2-catalyzed glycerol hydrolysis, it was found that the acidity of the catalyst could be controlled by tungsten oxide content and the glycerol conversion was largely improved with high 1,3-PDO selectivity. The technology largely improved the synthetic efficiency and is of potential industrial application value.
