    摘要: A process for producing secondary alkyl primary amines from nparaffins where a portion of the paraffin is nitrated to nitroparaffin along with the formation of nitrated and oxygenated by-products, where the nitroparaffin is essentially completely hydrogenated to the amine, and where the amine is separated from a mixture composed of unreacted paraffin and by products, which comprises catalytically hydrogenating the mixture composed of paraffin and by-products in the presence of a catalyst composed of alumina and a Group VIII metal at a temperature of from about 600* to 750*F. and recycling the hydrogenated product for nitration with the n-paraffin.

    摘要: This invention concerns the use of solubilized homogeneous ruthenium catalysts to initially and sequentially reduce the nitro group in mononitroaromatic substrates to the corresponding amine. The reduction must be carried out in a two component mixture consisting essentially of the mononitroaromatic and a mononitro ortho-substituted polyalkylaromatic component. In order to minimize the reduction of said nitropolyalkylaromatic component, the reduction should be halted when between about 80 to 95 % of the mononitroaromatic substrate present is reduced to the corresponding amine.
