Procedure

A reaction tube having a diameter of 32 mm and a length of 80 cm was used for reacting aniline and cyclohexanone to give diphenylamine. 200 ml (175.4 g) of catalyst were used which had been prepared according to German Offenlegungsschrift 3,801,754, Example 2, from spherical (2-6 mm) γ-Al2O3 by impregnating this support with 1% of Cr, 1.1% of Mn, 0.5% of Rh, 0.5% of Pt, 2.7% of NaOH and 2.7% of K2SO4.
