Provided by the present invention is a method for producing an alkanediol, such as 1,5-pentanediol, with a high reaction selectivity thereto by reacting a cyclic ether group-containing methanol such as tetrahydrofurfuryl alcohol by using a non-chromium catalyst not containing chromium atom. More specifically, the method is to produce an alkanediol having hydroxy groups at both molecular terminals shown by the formula (2), includes reacting a cyclic ether group-containing methanol shown by the formula (1) with hydrogen in the presence of a metal catalyst which contains copper atom, at least one co-existing atom selected from the group consisting of elements of the third to the sixth periods of the II to XIV groups (excluding chromium) in the periodical table and lanthanide elements.
本发明提供了一种通过使用不含铬原子的非铬催化剂与含环醚基甲醇(如四氢糠醇)反应生产烷二醇(如1,5-戊二醇)的方法,该方法具有较高的反应选择性。更具体地说,该方法是生产一种在两个分子末端都有羟基的烷二醇,如式(2)所示,包括在含有铜原子、至少一个共存原子的金属催化剂存在下,使式(1)所示的含环醚基甲醇与氢反应,该金属催化剂选自周期表中第二至第十四族第三至第六周期的元素(不包括铬)和镧系元素组成的组。
