Abstract
Flame retardant 3-(Hydroxyphenylphosphinyl) Propionic acid was prepared in this paper. The reaction conditions, such as reaction temperature, the ratio of reactants and exchangers were investigated. The yield of intermediate phenylphosphonic dichloride is up to 81%, and the yield of final production is 88%. The structure of 3-(hydroxyphenylphosphinyl) propionic acid was mearsured by FT-IR, and DSC.
