ABSTRACT:
This specification discloses a process for reacting an unsaturated hydrocarbon with a phosphorus chloride. The unsaturated hydrocarbon may be aromatic hydrocarbons, such as benzene, toluene or xylene or ethylene. The phosphorous chloride for reacting with the aromatic is a phosphorous trihalide such as a phosphorous trichloride or a phosphine dihalide such as phenylphosphine dichloride. The phosphorus chloride for reacting with the ethylene is phosphorus trichloride. The reaction is carried out in the presence of, as a catalyst, a crystalline aluminosilicate zeolite in the hydrogen form having a silica to alumina ratio of at least 12 and a constraint index of 1 to 12. The reaction is carried out at a temperature of 147.degree. C. to 475.degree. C., sufficient to effect reaction of the unsaturated hydrocarbon with the phosphorus chloride. The reaction product obtained from benzene and phosphorus trichloride is phenylphosphine dichloride, from benzene and phenylphosphine dichloride is diphenylphosphine chloride, and from ethylene and phosphorus trichloride is vinylphosphine dichloride.
