Method for preparing benzotriazole-alkylene bisphenol compound

The invention discloses a method for preparing a benzotriazole-alkylene bisphenol compound, and is characterized in that the method comprises the following steps: step 1, dissolving a first part of UV-P, dialkyl amine and paraformaldehyde in an alcohol solvent, and carrying out a stirring reaction at the temperature of 95-105 DEG C; step 2, after stirring for 24 h, drying the alcohol solvent by distillation in vacuum, to obtain an intermediate; step 3, dissolving the intermediate and a second part of UV-P in an aromatic hydrocarbon or alkane solvent, adding sodium methylate, heating the solution to 140-150 DEG C, and carrying out a reflux reaction for 10 h; step 4, after the reaction is finished, steaming out a part of the aromatic hydrocarbon or alkane solvent, and cooling and crystallizing to obtain a crude product; and step 5, recrystallizing the crude product to obtain a white solid, wherein the UV-P has the structural formula represented by the formula I, the white solid has the structural formula represented by the formula II. The preparation method has the beneficial effect of good yield.
