Abstract

Sodium tris-(4-methyl phenyl) phosphine tetrasulphonate is prepared by reacting tris-(4methyl-phenyl) phosphine with oleum and pouring the cooled reaction mixture into ethanol containing dissolved sodium. Similarly sodium monophenyl bis - (4 - chlorophenyl) - phosphine tetrasulphonate is prepared from phenyl-bis -(4-chlorophenyl)-phosphine.
