Procedure

91.1 g of benzophenone, 150 ml of tert-butylbenzene and 2 g of 200-mesh silica-alumina (Nikki Kagaku K.K., N-635) were fed to the same reactor as in Example 11. The reactor was heated, and ammonia gas was continuously fed to the reactor at a feed rate of 1.5 Nl/min, while keeping the contents at 170° C, and reaction was carried out under 8 atm. for one hour. The withdrawn gas was cooled and condensed tert-butylbenzene was refluxed into the reactor. After the completion of the reaction, benzophenoneimine was obtained in yield of 28%.
