PURPOSE: To obtain the subject compound useful as a raw material of cyclohexanol, etc., which is an intermediate of nylon, etc., in a high yield by carrying out an addition reaction between cyclohexene and acetic acid using a sulfuric acid-supported zirconium oxide and sulfuric acid as a catalyst.
CONSTITUTION: An addition reaction between cyclohexene and acetic acid is carried out using a sulfuric acid-supported zirconium oxide and sulfuric acid as a catalyst to obtain the objective compound. The ratio of acetic acid used to cyclohexene is ≥1 in which acetic acid is excessive, preferably within a range of 2-15 on molar ratio base. The reaction temperature is 0-500°C, preferably within a range of 30-300°C. The above-mentioned catalyst is a mixture composed of the sulfuric acid-supported zirconium oxide prepared by reacting zirconium hydroxide with dilute sulfuric acid and calcining the resultant product at ≥500°C and sulfuric acid. The amount of the catalyst used is 0.1-50 wt.%, preferably 1-30 wt.% based on cyclohexene.
