    摘要： A process for the production of predominantly primary and secondary amines and little or no tertiary amines by the reductive amination of aliphatic alcohols using a metal exchanged crystalline aluminosilicate catalyst. The catalyst has a silica/alumina ratio ranging from about 10:1 to 40:1, contains about 1 to 10% by weight of cobalt or nickel and about 0.05 to 5% by weight of at least one other metal. High conversion rates are achieved at moderate temperatures and pressures.

    摘要： The invention is directed to an improvement in a catalytic process for the ring hydrogenation of a methylenedianiline feedstock, including crude methylenedianiline. One component of the improvement is a pretreatment process which resides in passing the crude methylenedianiline feedstock over a ruthenium catalyst carried on a fixed bed support, cooling without venting, and then hydrogenation of the pretreated crude methylenedianiline feedstock over a rhodium catalyst or a mixed Rh/Ru catalyst carried on a monolith support and carrying out the ring hydrogenation in a batch reaction. Another component in the improvement is the employment of a catalyst comprised of rhodium and ruthenium carried on a monolith support.
