Hydrierung aromatischer Amine zur Herstellung ihrer entsprechenden ringhydrierten Verbindungen.

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: wherein R is hydrogen or C1-6 aliphatic, R1 and R2 are hydrogen or C1-6 aliphatic, A is C1-4, NH or 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.
