METHOD FOR PRODUCING PHENYLPHOSPHONIC ACID METAL SALT COMPOSITION, AND CRYSTAL NUCLEATING AGENT THEREFROM

摘要

A method for producing a phenylphosphonic acid metal salt composition, including reacting a phenylphosphonic acid compound (a) with a metal salt, metal oxide or metal hydroxide (b) that is present in an amount beyond the equivalent, the phenylphosphonic acid metal salt composition containing phenylphosphonic acid metal salt, and a surplus amount of the metal salt, the metal oxide or the surplus metal hydroxide (b). A crystal nucleating agent comprises the phenylphosphonic acid metal salt composition produced by the method.

1. A method for producing a phenylphosphonic acid metal salt composition, comprising reacting a phenylphosphonic acid compound (a) of formula [1]in which R1 and R2 are independently of each other hydrogen atom, C1-10alkyl or C1-10alkoxycarbonyl, with a metal salt, metal oxide or metal hydroxide (b) that is present in an amount beyond the equivalent,
wherein the phenylphosphonic acid metal salt composition contains phenylphosphonic acid metal salt, and a surplus amount of the metal salt, the metal oxide or the surplus metal hydroxide (b).
