Introduction	1, 3-benzenedimethanol is an organic intermediate, which can be reduced from isophthalonitrile to 1,3-benzene dimethyl amine, and then diazotization reaction to obtain 1,3-benzene dimethanol; Or reduction of ester group from dimethyl isophthalate to obtain 1,3-benzene dimethanol.
preparation	put isophthalonitrile into the autoclave, control the pressure of the autoclave to 4.0MPa, add anhydrous ethanol and potassium hydroxide, hydrogen gas was introduced and the reaction time was 10min to obtain 1, 3-xylylenediamine. Sulfuric acid was added to 1, 3-xylylenediamine, the pH was controlled to 5, stirred and heated, the temperature was controlled to 180-200 ° C., the reaction was 30-40min, and then the temperature was lowered to obtain 1, 3-benzenedimethanol.
