A suspension of 18.1 g of triphenylphosphine dichloride-chloroform adduct and 0.9 g of 5 percent rhodium-carbon in 100 ml of 1,2-dimethoxyethane was hydrogenated at 50° and 30 bar of hydrogen for 12 hours. After filtration of the catalyst and distillation of the solvent, 8.51 g (81%) of triphenylphosphine were obtained by chromatography on silica gel.
