실험 절차
As in Example 1, 597 g (2 mol) of stearic acid methyl ester (94%), 245.5 g (4 mol) of ethanolamine and 4 g (0.012 mol, 0.6 mol-%) of titanium tetrabutylate were reacted under nitrogen and normal pressure at 140°-175° C. to form stearic acid ethanolamine with removal of methanol by distillation. The excess ethanolamine was then distilled off in a water jet pump vacuum (20 hPa) at 115°-200° C. The temperature was then increased in an oil pump vacuum (0.007 hPa) to 220°-300° C., 2-heptadecyl-2-oxazoline and water distilling over.
