Preparation method of cyclic propyl phosphonic anhydride

The invention belongs to the technical field of organic synthesis and particularly relates to a preparation method of cyclic propyl phosphonic anhydride. The method comprises the steps of preparing propyl pyrophosphate from propenylphosphonic acid and acetic anhydride as reactants; preparing propyl phosphonyl chloride from propenylphosphonic acid and thionyl chloride as reactants; carrying out further reaction on the propyl pyrophosphate and the propyl phosphonyl chloride to prepare the cyclic propyl phosphonic anhydride. According to the prepared cyclic propyl phosphonic anhydride, the reaction yield is high and the total yield can reach 68-72%, the cyclic propyl phosphonic anhydride is low in cost and high in purity, the titration purity is greater than 99.5%, the content of free acid is smaller than 100ppm, the polymer content is low, and use of a lithium battery additive can be met. The preparation method is simple, safe, environment-friendly, high in efficiency, cheap and available in raw materials, wide in market prospect and suitable for massive production.
