Cobalt-doped hybrid materials consisting of metal oxides and carbon derived from chitin were prepared, characterized and tested for industrially relevant nitrile hydrogenations. The optimal catalyst supported onto MgO showed, after pyrolysis at 700 °C, magnesium oxide nanocubes decorated with carbon-enveloped Co nanoparticles. This special structure allows for the selective hydrogenation of diverse and demanding nitriles to the corresponding primary amines under mild conditions (e.g. 70 °C, 20 bar H2). The advantage of this novel catalytic material is showcased for industrially important substrates, including adipodinitrile, picolinonitrile, and fatty acid nitriles. Notably, the developed system outperformed all other tested commercial catalysts, for example, Raney Nickel and even noble-metal-based systems in these transformations.

, (2017/01/23)
The invention discloses a preparation method of a benzylamine compound. The method adopting an aryl methane compound as a raw material comprises the following steps: carrying out an NBS bromination reaction to synthesize a bromobenzyl compound, carrying out an N-hydrocarbylation reaction to synthesize a 1-benzylpyrrolidyl-2,5-dione compound, and carrying out a hydrolyzing reaction to obtain the benzylamine compound. The preparation method of the benzylamine compound has the advantages of wide source of the raw material, no need of separation of intermediates generated in above reactions, realization of an all-in-a-pot technology, simple operation, mild reaction conditions, high reaction yield, few three wastes, and convenience for industrial production.
