PROBLEM TO BE SOLVED: To provide a method for producing cyclohexanol, capable of increasing production amount of cyclohexanol per unit catalyst amount and obtaining cyclohexanol in a conversion higher than equilibrium conversion, directly and efficiently utilizing heat of reaction generated by reaction, because reaction and separation are simultaneously carried out in a distillation tower, simplifying the process compared with a conventional process and reducing equipment expenses required for reactor. SOLUTION: This method comprises producing cyclohexanol by equilibrium reaction of cyclohexene with water. In the method, a solid acid catalyst is previously packed in a part or all of the interior of a distillation tower and cyclohexene and water which are raw materials are fed as a liquid phase to the distillation tower and subjected to solid-liquid contact with the solid acid catalyst in the liquid phase, and a component rich in cyclohexanol which is a product of the reaction is obtained as a bottom component from the tower bottom. |
