PURPOSE: To produce the subject compound with a common reaction apparatus under mild conditions in high yield by dissolving a dihalomethyl compound of an aromatic hydrocarbon in a mixed solvent of water with a water-soluble organic solvent and hydrolyzing the solution in the presence of a silver salt compound. CONSTITUTION: A dihalomethyl compound of a monocyclic, bicyclic or polycyclic aromatic hydrocarbon is dissolved in a mixed solvent of water with an water-soluble organic solvent. Subsequently, the solution is subjected to hydrolysis in the presence of a silver salt compound such as silver nitrate. This method enables the production of an aromatic glycol in high yield of 99% even at normal temperature and under atmospheric pressure. The compound used as raw material is preferably e.g. a dihalomethyl derivative of benzene, toluene, ethylbenzene, naphthalene, anthracene, biphenyl, etc. The water-soluble organic solvent is preferably acetone, tetrahydrofuran, methyl formate, etc. The method enables the production of the objective compound with a simple apparatus in high yield without accompanying by-products. Further, the production cost can be reduced. |
