反応手順
0.5 mole of diphenylamine was taken together with 0.53 mole of n-butyl isocyanate and 1 g of di-n-butyl phosphate in 150 ml of xylene. The mixture was heated at 120° C. for 24 hours, with stirring, and then cooled to room temperature. After the product had been filtered off, washed with 100 ml of cold xylene and dried, 0.3 mole of N-n-butyl-N',N'-diphenylurea was obtained. Melting point: 92° C./yield: 60% of theory.
