Preparation method of 1,3-dimethyl-1,1,3,3-tetraethylene disiloxane

The invention relates to a preparation method of 1,3-dimethyl-1,1,3,3-tetraethylene disiloxane and belongs to the technical field of battery electrolyte additives. The preparation method comprises thesteps of taking methyldivinylchlorosilane as a raw material, adding an inorganic base solution, imidazole, a phase transfer catalyst and a polymerization inhibitor, carrying out a heating reflux reaction in an organic solvent, controlling reaction time to 5-10 hours, and after the reaction ends, performing liquid separation, water washing and distillation at 65-68 DEG C and 15 mmHg to obtain colorless and clear liquid. The preparation method is simple, easy to operate and high in yield, the reaction steps are simple, and the purity is high.
