Continuous preparation method of tri(2,3-dichloropropyl)phosphate

The invention relates to a continuous preparation method of tri(2,3-dichloropropyl)phosphate, which includes the steps of: according to ratio, continuously adding phosphorus oxychloride, epoxy chloropropane and a catalyst into esterification reaction kettles to perform a reaction, wherein the esterification reaction is carried out at different temperatures in different reaction kettles, thereby obtaining an esterification reaction crude product in an auto-overflow manner between the reaction kettles; and water-washing and neutralizing-washing the crude product and performing pressure reduced dehydration to obtain a tri(2,3-dichloropropyl)phosphate-TDCP finish product. The method allows continuous production of the tri(2,3-dichloropropyl)phosphate-TDCP, is low in labor intensity, has simple operations and short production period, is economical and environment-friendly, is high in production efficiency, can satisfy demands in industrial-scale production, and is suitable for being industrially promoted.
