Versuchsvorschrift

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.
