An improved process for producing an alcohol by hydrating an olefin wherein the improvement comprises hydrating an olefin in the presence of a hydrogen-type catalyst having a silica/alumina molar ratio of 20 to 500 and a solvent using either:
A. hydrogen-type mordenite or hydrogen-type zeolite Y, and a sulfone; or
B. hydrogen-type crystalline aluminosilicate in which the entrance of the main void is formed by a 10-membered or 12-membered oxygen ring, and a C2 to C5 oxy acid or the lactones, lactides, methyl or ethyl esters thereof.
一种通过水合烯烃生产醇的改进工艺,其改进包括在二氧化硅/氧化铝摩尔比为 20 至 500 的氢型催化剂和溶剂存在下水合烯烃:
A. 氢型莫来石或氢型沸石 Y,以及砜;或
B. 氢型结晶铝硅酸盐,其中主空隙入口由 10 元或 12 元氧环和 C2 至 C5 氧酸或其内酯、内酯、甲基或乙基酯形成。
