Versuchsvorschrift

The reaction apparatus was filled with 2 kg (11.8 mol) of diphenylamine and 200 g (1.74 mol) of phosphoric acid. Methanol was introduced at a rate of 50 ml/h for 40 hours at a reaction temperature of 200°C. The reaction mixture was then cooled to 140°C and the upper phase run-off. 1.822 kg of N-methyldiphenylamine (99.2 %) were obtained.
