Abstract
Disclosed is a method for hydrating a cycloolefin, in which the hydration is conducted in a reaction system comprising a continuous aqueous phase including water and a crystalline aluminosilicate catalyst suspended therein and an oil phase including a cycloolefin, while dispersing the oil phase as globules having a specific diameter. By the method of the present invention, not only can a cyclic alcohol be produced at high selectivity and in high yield, but the activity of the catalyst can also be stably maintained at a high level for a prolonged period of time, and the produced cyclic alcohol can be readily separated.
