ABSTRACT:
This invention relates to an improved hydrogenation and isomerization process wherein aromatic amines are hydrogenated to their ring hydrogenated counterparts and substantially isomerized to their thermodynamic form. These aromatic amines are presented by the formulas: ##STR1## wherein R is hydrogen or C.sub.1-6 alkyl, R1 and R2 are hydrogen or C.sub.1-6 aliphatic, A is C.sub.1-4 or NH; n is 0-2, x is 1-3 and y is 0 to 2 except the sum of the y groups must be at least 1.
