Overview	diphenyl phosphinic chloride can be used to prepare composite retarder for concrete, the flame retardant diphenylphosphinyl-N-caged phosphate amine compound and the like can be prepared by reacting diphenylphosphine chloride and trifluoromethanesulfonic acid.
preparation	in a ML reaction bottle after nitrogen replacement, 27.8g of triphenylphosphine oxide and 88.2G of diphenylphosphine chloride (mass ratio 1:3.17) were placed. 0.56g of trifluoromethanesulfonic acid (2% of the mass of triphenylphosphine oxide) was heated to 150 ° C. For 12 hours. After cooling to room temperature, the vacuum pump was turned on, and after the vacuum degree reached 0.098MPA, the temperature was slowly raised, and a mixture of diphenylphosphine chloride and diphenylphosphinyl chloride was intercepted.
purposes	mainly used in the synthesis of pesticides, used as flame retardants, etc. used in the synthesis of bidentate ligands, peptide coupling agents.
