    • PURPOSE: Provided is a process for producing 1,3-alkanediol from a 3-hydroxy ester compound by using a hydrogenation catalyst having high activity and high selectivity. CONSTITUTION: The 1,3-alkanediol is produced by hydrogenating the 3-hydroxy ester compound such as 3-hydroxy methyl propanoate in the presence of the catalyst in a mixed solvent comprising an alcohol solvent and a solvent having a higher boiling point than the 1,3-alkanediol by a liquid-gas phase method, wherein the catalyst is produced by adding an alkali precipitant, such as an alkali carbonate or sodium hydroxide, to a water solution of copper salts to produce particles and then aging by adding colloidal silica. The catalyst has a weight ratio of copper oxide(CuO) and silica(SiO2) being 9:1-5:5.
    • 目的:提供使用具有高活性和高选择性的氢化催化剂由3-羟基酯化合物生产1,3-链烷二醇的方法。 构成:通过在催化剂存在下,在含有醇溶剂和沸点比1的沸点高的溶剂的混合溶剂中,将3-羟基酯化合物如3-羟基甲基丙酸酯氢化,生成1,3-链烷二醇 的3-链烷二醇,其中通过将碱如碳酸盐或氢氧化钠等碱性沉淀剂加入到铜盐水溶液中而制备催化剂,从而制备颗粒,然后通过加入胶体二氧化硅来老化。 催化剂的氧化铜(CuO)和二氧化硅(SiO 2)的重量比为9:1-5:5。
