The invention discloses a technology for preparing 2,3,5,6-tetrafluoro-1,4-benzenedimethanol, and belongs to the technical field of fine chemical synthesis. The technology includes the following reaction steps that (1) dry hydrogen chloride gas is led into 2,3,5,6-tetrafluoro-1,4-terephthalonitrile in an ether solvent for reaction, then low carbon alcohol is added for reaction, and a solution of 2,3,5,6-tetrafluoro-1,4-imino-terephthalate is obtained; (2) the 2,3,5,6-tetrafluoro-1,4-imino-terephthalate is reacted with water, an organic phase substance is collected and washed with water to be neutral, the solvent is removed in a vacuum distillation mode, and 2,3,5,6-tetrafluoro-1,4-terephthalic acid diester is obtained; (3) the 2,3,5,6-tetrafluoro-1,4-terephthalic acid diester is subjected to a catalyzed hydrogeneration reduction reaction, an organic phase substance is collected, cooled, subjected to suction filtration and dried, and the 2,3,5,6-tetrafluoro-1,4-benzenedimethanol is obtained. The technology has the advantages that the raw materials are low in cost, operation is easy and convenient, and high-concentration acid wastewater is avoided.
