PROCESS FOR INCREASING THE SELECTIVITY OF THE HYDROGENATION OF 4,4'-DIAMINODIPHENYLMETHANE TO 4,4'-DIAMINODICYCLOHEXYLMETHANE IN THE PRESENCE OF AN N-ALKYL-4,4'-DIAMINODIPHENYLMETHANE

The invention relates to a process for increasing the selectivity of the hydrogenation of 4,4'-diaminodiphenylmethane (4,4'-MDA) to diaminodicyclohexylmethane (4,4'-HMDA) by catalytic hydrogenation of a mixture containing 4,4'-MDA as the main component and its mono-N-methyl derivative as a secondary component. According to the invention, the hydrogenation is terminated before a conversion of 4,4'-MDA to 4,4'-HMDA of 99% is achieved. Under these conditions, a substantially smaller proportion of the N-methyl-4,4'-MDA is hydrogenated to N-methyl-4,4-HMDA.
