The present invention relates to processes for the catalytic hydrogenation of aromatic amines to their acyclic counterparts using a ruthenium catalyst on a lithium aluminate support. The hydrogenation process comprises contacting an aromatic amine with hydrogen in the presence of a ruthenium catalyst under temperature and pressure conditions suitable to effect ring hydrogenation. The process is especially useful for hydrogenating aniline to cyclohexylamine.

This invention relates to an improved hydrogenation process for the preparation of etheramines. In the process, cyanoethylated alcohols, i.e., the reaction product of an alcohol with (meth)acrylonitrile, are contacted with hydrogen in the presence of a sponge cobalt catalyst. The improvement in the process resides in effecting the hydrogenation process utilizing a cyanoethylated alcohol feedstock contaminated with byproduct acrylonitrile and utilizing a solvent that solubilizes byproduct (meth)acrylonitrile present in the feedstock. Specific classes of solvents employed are ethers and amides.
