| titleOfInvention | Production of 2-chloroformylethylmethylphosphinic acid chlorides |
| abstract | The invention relates to a process for making 2-chloroformylethylmethylphosphinic acid chlorides of the general formula: <IMAGE> in which R1 and R2 each stand for hydrogen or CH3. To this end, methyldichlorophosphane is reacted with acrylic acid, methacrylic acid or crotonic acid at elevated temperature. More particularly, a solution of methyldichlorophosphane in phosphorus trichloride, the solution originating from a reaction of phosphorus trichloride with methane at temperature higher than 500 DEG C., is used. The reaction is effected at temperatures ithin the range 50 DEG to 90 DEG C. in the presence of hydrogen chloride; and the phosphorus trichloride is distilled off. |
