A process for hydrogenating an aromatic nitro compound according to the invention comprises

Process for the conversion of aromatic nitro compound into amines

A process for providing methylene-bridged polyphenyl polyamines from aniline and formaldehyde according to the invention comprises the subsequent steps of a) condensing aniline and formaldehyde; b) reacting, in a first catalytic reaction step, said condensate over a solid catalyst, whereby an intermediate mixture is provided; c) converting, in a subsequent catalytic reaction step, said intermediate mixture into methylene-bridged polyphenyl polyamines in presence of a subsequent solid catalyst, thereby providing said methylene-bridged polyphenyl polyamines.

Process for the production of methylene-bridged polyphenyl polyamines

Method of preparing diaminodiphenylmethane and higher homologues thereof from aniline and formaldehyde in the presence of heterogeneous solid acid catalysts selected from (a) delaminated zeolites and/or (b) metal silicate catalysts having an ordered mesoporous pore structure and/or (c) delaminated phyllosilicates.
