| titleOfInvention | Method for preparing alkylphosphonic acid, aralkylphosphonic acid and salts thereof |
| abstract | The alkyl phosphonic acid alkyl ester or the aralkyl phosphonic acid alkyl ester represented by the following general formula (1) is added dropwise to the hydrolysis reaction while maintaining the temperature range of 120 to 200 ° C. in the presence of a nonvolatile acid. Process for producing alkyl phosphonic acid or aralkyl phosphonic acid represented by the following general formula (2), characterized by having a step (A); Following the said process (A), it has a process (B) or (C) which adds an amine or an alkali metal hydroxide, The alkyl phosphonic acid amine salt or the aralkyl phosphonic acid amine salt, or the alkyl phosphonic acid alkali metal salt Or a method for producing an alkali metal phosphonic acid alkali salt; And following step (C), a step (D) of adding a metal chloride other than an alkali metal and performing a salt exchange reaction. The method for producing an alkylphosphonic acid metal salt or an aralkylphosphonic acid metal salt. Provided that R 1 in General Formulas (1) and (2) has a substituent or an unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aralkyl group having 7 to 20 carbon atoms, R 2 and R 3 are each independently an alkyl group having 1 to 8 carbon atoms or a hydrogen atom, and at least one of R 2 and R 3 is an alkyl group having 1 to 8 carbon atoms. |
