실험 절차

250 g of urea were continuously introduced into a decomposer in the course of 2 hours. The pyrolysis gases were introduced into a melt of 1200 g of dodecylamine at a temperature of 80 to 90° C. After completion of the reaction, the excess dodecylamine was distilled off in vacuo and the residue was recrystallized from chloroform. 598.9 g, i.e. 63% of theory, of dodecylurea having a melting point of 105 to 107° C were obtained in this way.
