    摘要: Embodiments of the present invention disclose a process for the co-production of bis(para-aminocyclohexyl) methane (PACM). Also disclosed are articles of manufacture made using PACM produced by methods of this invention. The methods of the present invention generally include a first mixture having methylene di-aniline (MDA) and a second aromatic amine. The first mixture has less than 15% polymeric MDA by weight and the second aromatic amine is present in an amount to render the first mixture a liquid. The first mixture is hydrogenated to produce a product mixture comprising PACM and at least one second non-aromatic amine.
