Versuchsvorschrift

6.2 g (0.022 mol) of stearic acid and 6 g (0.022 mol) of 2-aminooctadecane-1,3-diol were mixed in a tube and irradiated with the apparatus used in Example 1, under the same frequency and power conditions. After an irradiation of 18 minutes at 140° C.±5° C., the reaction mixture was solubilized in a mixture of 80 ml of ethyl acetate and 40 ml of heptane. The precipitate obtained was recrystallized from ethanol and 8.1 g of expected pure product were obtained with a yield of 72%.
