Abstract
Procedure for obtaining diaminodiaryl methanes, with a higher proportion of 2,4'-diaminodiarylmethane, by heating a mixture of a polyarylamine of the general formula ** (See formula) ** where n represents an integer from 0 to 8, R means hydrogen, a halogen atom, an alkyl group with 1 to 4 carbon atoms, an alkoxy group with 1 to 4 carbon atoms or an aralkyl group with 7 to 10 carbon atoms, and R1 means hydrogen or an alkoxy group with 1 to 4 carbon atoms, with a monoarylamine of general formula wherein R has the meaning indicated above, in the presence of an acidic reaction catalyst; characterized in that the reaction is carried out in the presence of a catalyst consisting of an inorganic substance, insoluble in the amines used, solid, which does not melt under the reaction conditions.
