실험 절차

A catalyst consisting of 1.0% by weight of palladium and 0.5% by weight of praseodymium oxide, the remainder being aluminum oxide, in extrudate form is introduced into a 1 l cylindrical reaction tube and is heated to 200° C. A mixture of 60 g of 2,6-dimethylphenol and 360 g of liquid ammonia per hour is passed over this catalyst bed. At the same time, 100 liters (S.T.P.) of hydrogen are passed in co-current through the reaction tube under a pressure of 200 bar. The reaction product which leaves the tube is cooled under superatmospheric pressure and is then let down. About 62 g of crude product, which gives 60 g of pure 2,6-dimethylcyclohexylamine (corresponding to a yield of 96%) on distillation, are thereby obtained per hour.
