4 g. (0.1 mol) of sodium hydroxide, dissolved in 10 ml of water, and 7.3 g. (0.1 mol) of diethylamine were simultaneously added to a solution containing 23.35 g. (0.1 mol) of lauric N-chloramide in 200 ml of tertiary butanol. The resulting mixture was heated to 40° C., and then allowed to react for 30 minutes at this temperature. Any precipitated sodium chloride was removed by filteration and the filtrate was concentrated producing a residue. The residue was taken up in 100 ml of acetone and filtered to yield 24.3 g. (90% yield) of N,N-diethyl-N'-n- undecyl urea of the formula ##STR4## having a melting point of 33°-35° C. and the following analysis:
