The invention discloses a microwave synthesis method of polyester polyol used for polyurethane soles. The microwave synthesis method takes binary acid and diol with molar ratio of 1:1-4 as raw materials to obtain polyester polyol used for polyurethane soles by microwave heating and reaction for 10-30 minutes at reaction temperature of 200-240 DEG C under the actions of catalysts. The number average molecular weight of the prepared polyester polyol is 1000-3000g/mol, and acid value is lower than 0.1mgKOH / g. Compared with the traditional methods, the microwave synthesis method has the advantages of short reaction time, low energy consumption, good product quality and the like, and solves the problems of long reaction time and large energy consumption of the polyester polyol used for polyurethane soles.
