Abstract
A method for producing a cycloalkanol in high yield by hydrating cycloalkene with a specific catalyst is disclosed. The catalyst is obtainable by ion-exchanging all or a part of the cations of a crystalline gallium silicate with hydrogen ions. It has a specific composition defined by the general formula and is characterized by the X-ray diffraction pattern.
