A catalyst which contains at least one element selected from the group consisting of Group V elements, Group VI elements, Group VII elements, Group VIII elements, Group IX elements, Group X elements, and Group XI elements in the periodic table, and is to be used for subjecting an epoxy alcohol represented by a general formula (1) to a hydrogenolysis reaction in the presence of at least one solvent selected from the group consisting of ethers, esters, aromatic hydrocarbon compounds, alicyclic hydrocarbon compounds and aliphatic hydrocarbon compounds. By use of such a catalyst, a both end-hydroxyl group-terminated diol having a high purity can be produced efficiently.
一种催化剂,它含有至少一种选自元素周期表中第 V 族元素、第 VI 族元素、第 VII 族元素、第 VIII 族元素、第 IX 族元素、第 X 族元素和第 XI 族元素组成的组的元素,用于在至少一种选自醚、酯、芳香烃化合物、脂环烃化合物和脂肪烃化合物组成的组的溶剂存在下,使通式(1)代表的环氧醇进行氢解反应。通过使用这种催化剂,可以高效地生产出纯度较高的双端羟基封端二元醇。
