実験手順
360 g of hydrazodicarbonamide, 807 g of stearyl amine and 1 ml of tin(II)dioctoate are stirred in 1 liter of N-methyl pyrrolidone for 4 hours at 175° C. and for 6 hours at 200° C. A deposit precipitates on cooling and is isolated by filtration under suction and washed with water, giving 955 g (90% of the theoretical) of 4-stearyl-1,2,4-triazolidine-3,5-dione in the form of colourless crystals melting at 118° to 120° C.
