PROBLEM TO BE SOLVED: To efficiently produce cumene important as a raw material, etc., for producing phenol and acetone by oxidation and degradation by reacting benzene with isopropyl alcohol in the presence of zeolite and water in a liquid phase. SOLUTION: This method for producing cumene by reacting benzene with isopropyl alcohol in a liquid phase comprises the reaction in the presence of a zeolite such as mordenite, having 100-300 ratio of silica to alumina, and water of an amount not larger than the amount soluble in the reaction raw material at 150-250 deg.C under a pressure sufficient to keep the reacting material in a liquid phase at the temperature to effectively provide the objective cumene. The objective cumene is extremely important compound largely used in the production of phenol and acetone by oxidizing the cumene to provide cumene hydroperoxide and degrading the cumene hydroxide in the presence of an acid. |
