发明名称 METHOD FOR PRODUCING HALOGEN-SUBSTITUTED BENZENEDIMETHANOL
摘要 Disclosed is a method for producing a halogen-substituted benzenedimethanol represented by the formula (2) below, which is characterized in that a halogen-substituted terephthalic acid represented by the formula (1) below is reacted with a boron hydride compound in an organic solvent, and the thus-obtained reaction mixture is brought into contact with hydrogen chloride at a temperature of 40-70°C. (1) (In the formula, X1, X2, X3 and X4 independently represent a hydrogen atom or a halogen atom, provided that all of X1, X2, X3 and X4 are not hydrogen atoms at the same time.) (2) (In the formula, X1, X2, X3 and X4 are as defined above.)
