Reaction Conditions

Reaction Steps

In a steel autoclave fitted with a stirring apparatus and a product draw off system retaining the catalyst in the reactor can be placed 200 parts of 4-aminodiphenylmethane as described in British Patent 764,633 and 100 parts of a finely divided 5% ruthenium on an alumina support and 15 parts of potassium methoxide. The mixture within the autoclave can then be heated to 290°C with stirring and hydrogen added to maintain a pressure of 290 atmospheres for 20 minutes. The resulting mixture can then be freed of catalyst by filtration and distilled to strip off solvent. Final distillation under vacuum can then be used to provide the desired product, 4-aminodicyclohexylmethane, which is a colorless viscose liquid.
