Synthesis

(1) adding triphenyl phosphine to an organic solvent, adding ethyl chloride in a dropwise manner, heating to a temperature of 120-160℃ after the adding, adjusting the reaction pressure to 8-12 kg/cm2, and carrying out a thermal insulation reaction for 30-40 h; (2) after completing the thermal insulation reaction, cooling to a room temperature, reducing the pressure to a normal pressure, and carrying out centrifugation on the material obtained after the reaction; and (3) drying the centrifugal precipitate so as to obtain the ethyl triphenyl phosphonium chloride.
