Reaction Steps
In a reactor wherein air was replaced by N2, 300.0 g of (1.1 mol) triphenyl phosphine and 500 mL of methanol were added and heated to 60° C. 321.8 g (1.1 mol) of trifluoromethanesulfonimide was then added dropwise under strong stirring, and 176.0 g (2.0 mol) of ethylene carbonate was also added after a half hour of reaction. The reaction mixture was transferred to an autoclave, wherein air was removed prior to heating. After 4 hours of reaction at temperature of 160° C. and at pressure of from 1.4 MPa to 1.5 MPa, the crude product was obtained after distilling off the unreacted materials and solvent. 616.3 g of 2-hydroxyethyl triphenyl phosphonium bis(trifluoromethyl sulfonyl) amide was obtained after washing and drying at 60° C. and 0.1 kPa for 4 hours.
