实验步骤: 22 g of 1-(2-hydroxyethyl)-2-undecyl-2-imidazoline and 300 ml of water was stirred at 40°-50° C. for 24 hours. The resulting soapy solution was salted with 50 g of NaCl and then extracted with 500 ml ethyl acetate. The organic layer was dried, filtered and concentrated to give 23 g of solid. This material was dissolved in hexane by heating at 50 C. for 2 hrs., then cooled to room temperature and filtered to afford 18.8 g of pure product, m.p. 92°-94° C. extracted with 500 ml ethyl acetate The organic layer was dried filtered concentrated

实验步骤: 34 g (127 mmoles) 1-(2-Hyrdoxyethyl)-2-undecyl-2-imidazoline was dissolved in 300 ml of hexane and 8.5 g (14.2 mmoles) of acetic acid in 50 ml of hexane were reacted. The precipitate was filtered and then dried at 40°-50° C. under high vacuum for 5 hours. Yield 40.7 g (97.8%). The compound was hydroscopic and was hydrated to a gel upon absorbing moisture. The precipitate was filtered dried at 40°-50° C. under high vacuum for 5 hours upon absorbing moisture

实验步骤: 58.7 g (564.4 mmoles) of 2-(2-aminoethylamino)ethanol and 122.8 g (538.6 mmoles) of ethyl dodecanoate were heated at 125° C. and ethanol was removed by distillation. 100 ml of toluene was cautiously added and water was removed azeotropically on further reflux. The reaction mixture was fractionally distilled to give 100.2 g (69.5%) of pure product, m.p. 40°-42° C. ethanol was removed by distillation 100 ml of toluene was cautiously added water was removed azeotropically on further reflux The reaction mixture was fractionally distilled

实验步骤: Fifty-three and seven tenths g (53.7 g, 0.2 mol) of 1-(2-hydroxyethyl)-2-undecyl-2-imidazoline was melted, and 60 g (0.6 mol) of ethyl acrylate was added. The mixture was reacted at a temperature of 60°-65° C. for 4 hr. in a substantially anhydrous condition. After the reaction, the excess ethyl acrylate was removed by vacuum-topping the reaction mixture at a temperature of 30°-40° C. Seventy-three and a half g (73.5 g) of 1-(2-hydroxyethyl)-2-(α-ethoxycarbonylethyl-undecyl)-2-imidazoline was obtained as a slightly yellow viscous liquid. The mixture was reacted at a temperature of 60°-65° C. for 4 hr After the reaction the excess ethyl acrylate was removed by vacuum-topping the reaction mixture at a temperature of 30°-40° C
