実験手順: A mixture of 13.9 g (0.055 mole) N-(2-hydroxyethyl)lauramide, 13.9 g (0.05 mole) 3(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid, 0.5 g Tyzor TBT catalyst and 100 ml xylene was refluxed until evolution of water ceased (3 hours). The xylene was removed by vacuum stripping. The residue was taken up in acetonitrile. White crystals separated upon cooling at about -10° C. The acetonitrile was decanted and the recrystallization was repeated. The last traces of acetonitrile were removed under vacuum, and the title product thus obtained was a yellow oil at room temperature. (3 hours) The xylene was removed by vacuum stripping White crystals separated The acetonitrile was decanted the recrystallization The last traces of acetonitrile were removed under vacuum

実験手順: 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. The mixture was refluxed for 6 hours Toluene was gradually removed The distillate was collected in a Stark & Dean trap The toluene was removed by vacuum stripping the residue was crystallized from n-hexane
