| titleOfInvention | Process for producing alkyl phosphonic acid |
| abstract | The invention relates to a method for preparing alkyl phosphonic acid, which comprises the following steps: (1) an alkali metal reacts with phosphite ester to obtain phosphite ester; (2) the phosphate ester reacts with halogenated alkane to obtain alkyl phosphonate ester; and (3) the alkyl phosphonate ester is hydrolyzed to obtain the alkyl phosphonic acid. The method has the advantages of reasonable reaction steps which are carried out at normal pressure, mild and smooth process condition, simple process flow, higher purity of obtained products, comparatively stable yield, and better industrialized prospect, and can be used for preparing various alkyl phosphonic acids, such as methylphosphoric acid, ethylphosphonic acid, propylphosphonic acid and the like. |
