Title: PROCESS FOR PREPARING PHENYLCHLOROPHOSPHINES
Abstract:
The invention concerns a process for preparing phenylchlorophosphines of formula (I): Clx-p-(-C6H5)y, in which x has the value 1 or 2, and the total of x + y is 3, or mixtures of compounds (I) by reacting phosphorus trichloride (PCl3) with triphenylphosphine (P-(C6H5)3) in a molar ratio of PCl3 to P-(C6H5)3 of between 1:5 and 5:1 at a temperature of between 280 and 450 °C, the mixture produced by this reaction, before being distilled, being reacted with between 1.5 and 15 mol elemental chlorine per mol of elemental phosphorus present in the reaction mixture.
