Abstract
This invention relates to an improved hydrogenation process wherein aromatic amines are hydrogenated to their ring hydrogenated counterparts. These aromatic amines are presented by the formulas: ##STR1## wherein R is hydrogen or C.sub.1-6 aliphatic, R.sub.1 and R.sub.2 are hydrogen or C.sub.1-6 aliphatic, A is C.sub.1-4, NH or ##STR2## n is 0-2, x is 1-3 and y is 1 to 2 except the sum of the y groups in Formula I excluding A may be 1. The improvement resides in the use of a rhodium catalyst carried on titania support.
