| titleOfInvention | Production of pure methyldichlorophosphane |
| abstract | Pure methyldichlorophosphane is recovered from a mixture containing phosphorus trichloride and methyldichlorophosphane as its principal constituents by distillation in two stages. Phosphorus trichloride and other low-boiling material are distilled off overhead in the first stage and methyldichlorophosphane is distilled off from high-boiling material in the second stage, the latter being fed with base product coming from the first stage. More specifically, there is dissolved in the said mixture, prior to admitting it to the first distillation stage, 0.01 to 1 weight % of an organic barium compound or 0.1 to 10 weight % of a non-ionic surfactant, and the base product coming from the first distillation stage is admixed, prior to admitting it to the second distillation stage, with 1 to 10 weight % of phosphorus oxychloride. |
