Versuchsvorschrift

To a solution of 24 g (0.4 mole) ethanolamine in 100 ml toluene was added 40 g (0.2) lauric acid at 50° C. The mixture was refluxed for 6 hours. Toluene was gradually removed to increase the final pot temperature to 140° C. The distillate was collected in a Stark & Dean trap. The toluene was removed by vacuum stripping and the residue was crystallized from n-hexane. The title compound (44 g) thus obtained melted at 80°-84° C.
