实验步骤: 14.1 g of dodecylamine (0.076 mol) dissolved in 20 ml of chloroform were added dropwise at room temperature with stirring to 100 ml of a solution of 10 g of triethylammonium isocyanate (0.069 mol) in chloroform, prepared according to Example 1. After completion of the addition, the mixture was subsequently stirred at room temperature for 24 hours and heated to reflux for 1 hour. The solvent was evaporated and the residue was recrystallized from chloroform. 9.45 g, i.e. 60% of theory, of dodecylurea were obtained in this way. were added dropwise at room temperature prepared After completion of the addition heated to reflux for 1 hour The solvent was evaporated the residue was recrystallized from chloroform

实验步骤: 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. After completion of the reaction the excess dodecylamine was distilled off in vacuo the residue was recrystallized from chloroform
