摘要： The manufacture of trialkyltrithiophosphites by reacting an excess of an alkyl mercaptan with phosphorous trihalide and scrubbing of noncondensible reactor off-gases with strong caustic solution, continuing the scrubbing until the strong caustic solution becomes spent though still mildly alkaline when the alkyl mercaptan separates into a separate phase. The mercaptans are separated to recycle. The trialkyltrithiophosphite can be oxidized to trialkyltriphosphorothioate with further stripping and recovery of remaining mercaptans.
