HYDROGENATION OF AROMATIC AMINES TO PRODUCE THEIR RING HYDROGENATED COUNTERPARTS |
摘要 |
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: <CHEM> wherein R is hydrogen or C1-6 aliphatic, R1 and R2 are hydrogen or C1-6 aliphatic, A is C1-4, NH or <CHEM> 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. |
