4477-28-5 - Production method
two methods, p-nitrochlorobenzene method and diphenylamine method, are used in China. 1. The p-nitrochlorobenzene method is obtained by condensation of p-nitrochlorobenzene with aniline and salicylic acid, then reduced and distilled by sodium sulfide, and then treated by hydrochloric acid into salt, then filtered and dried. 2. Diphenylamine method is obtained by coupling diphenylamine and aniline diazonium salt, and then hydrolytic reduction, salt formation, re-filtration and drying. Raw material consumption (kg/t)(1) p-nitrochlorobenzene method nitrochlorobenzene 1065 aniline 1200 salicylic acid 273(2) diphenylamine method diphenylamine 1180 chlorobenzene 900 methanol 570
