A 2, 2 the [...] -dihydroxy-4-methoxy benzophenone synthetic method

The invention provides a synthetic method of 2,2'-dyhydroxyl-4-methoxyl diphenyl ketone. The method comprises the following steps: (1) reacting m-benzene dimethylether with o-methoxybenzoyl chloride for 1-10 hours at the temperature of 0-80 DEG C under the irradiation of light having specific wavelength to obtain an intermediate product 2,2',4-triethoxy diphenyl ketone; (2) carrying out a selective demethylation reaction on the intermediate product 2,2',4-triethoxy diphenyl ketone obtained in the step (1) and a demethylating reagent for 5-16 hours at a reaction temperature of 40-120 DEG C and then performing water washing, liquid separation and recrystallization after the reaction ends to obtain 2,2'-dyhydroxyl-4-methoxyl diphenyl ketone (II). The method is low in reaction energy consumption, high in raw material recovery rate, simple in aftertreatment and small in environment pollution, so the method satisfies the development of environmental-friendly chemistry.
