FIELD: chemistry.
SUBSTANCE: invention relates to the method of obtaining diaminephenylmethane and its highest homologues by the condensation of aniline and formaldehyde in the presence of heterogeneous solid acid catalysts, which are characterised by the fact that the utilised catalysts are catalysts selected from (a) split zeolites and/or (b) alumo-silicate catalysts, which have the regulated hexagonal mesoporous structure with the size of 3-10nm.
EFFECT: it makes it possible to get diaminephenylmethane with the increased contents of primary amines.
