(57) [Problem] To provide a method for industrially efficiently producing cumene by reacting isopropyl alcohol and benzene in a liquid phase in the presence of a zeolite catalyst. SOLUTION: In producing cumene by reacting benzene and isopropyl alcohol in a liquid phase, a method for producing cumene, comprising reacting in the presence of zeolite and water. According to the method of the present invention, the production of diisopropyl ether as a by-product is suppressed to a low level, and the accumulation of diisopropyl ether in the separation and purification system is reduced. it can. |
