The invention relates to a method for synthesizing polyoxymethylene dimethyl ether by using polyoxymethylene, and the method is mainly used for solving the problems of low reaction efficiency of the traditional catalyst and relatively high cost caused by taking trioxymethylene as a raw material. The problems are better solved according to the technical scheme that methanol, dimethoxymethane and polyoxymethylene are used as raw materials, wherein the mass ratio of methanol to dimethoxymethane to polyoxymethylene is (0-10):(0-10):1, the dosages of methanol and dimethoxymethane cannot be simultaneously equal to zero, the raw materials are in contact with a catalyst to react to generate polyoxymethylene dimethyl ether under the conditions that the reaction temperature is 70-200 DEG C and the reaction pressure is 0.2-6MPa, the dosage of the catalyst accounts for 0.05-10% of the weight of the raw materials, and the adopted catalyst comprises the following components in parts by weight: 30-80 parts of molecular sieve carriers (a) and 20-70 parts of rare earth modified solid super acid (b). The method can be used for industrial production of polyoxymethylene dimethyl ether.
