description	The invention relates to the field of chemical engineering, in particular to a method for continuously recovering 3, 3 ', 5, 5'-tetramethyl biphenyl diquinone. The method comprises the following steps: cooling the polyphenyl ether reaction mother liquor synthesized by a precipitation method, and keeping the temperature of the reaction mother liquor at 10-15 DEG C by controlling the feeding speed; filtering the cooled reaction mother liquor in a stirring state; mixing filter residues obtained by filtering with methylbenzene, and transferring impurities in the filter residues into the methylbenzene; mixing filter residues obtained after treatment with water, and transferring impurities in the filter residues into the water; according to the method, continuous recovery of the 3, 3 ', 5, 5'-tetramethyl biphenyl diquinone can be achieved, the wall sticking phenomenon is avoided, the yield of the finished product can be increased, the quality of the finished product can be improved, and the method is simple, feasib
