ABSTRACT:
Chlorodiphenylphosphane is prepared by reacting dichlorophenylphosphane with triphenylphosphane at temperatures between about 300.degree. and 700.degree. C. In the temperature range from about 300.degree. to 500.degree. C., this reaction is preferably carried out under elevated pressure, in particular under the autogenous pressure which becomes established in a sealed system, while atmospheric pressure is preferably used in the temperature range from about 500.degree. to 700.degree. C.
The reaction product chlorodiphenylphosphane is in the main an intermediate in various fields, such as, for example, the polymer sector.
