ABSTRACT:
Methyldichlorophosphane is made by reacting methane with phosphorus trichloride in contact with carbon tetrachloride at temperatures higher than 500.degree. C. To this end, the starting reactant mixture is admixed with 2 to 7 mol % of reaction-initiating carbon tetrachloride, based on phosphorus trichloride; the carbon tetrachloride is reacted to an extent of 50 to 80% by varying the reaction temperature within the range 550.degree. to 650.degree. C for constant residence times of 0.1 to 0.9 second; and resulting reaction mixture containing a residual analytically detectable 20 to 50% proportion of the carbon tetrachloride used is condensed out.
