Abstract

A process for preparing methane diphenyl diamine (MDA) or a mixture of methane diphenyl diamine (MDA) and its higher homologues with a controlled isomer distribution using a silanised zeolite have "shape selectivity". The mixture contains compounds having the following general formula (I): where R represents a hydrogen atom or a C<SUB>1 </SUB>to C<SUB>8 </SUB>(iso) alkyl group, a C<SUB>4 </SUB>to C<SUB>10 </SUB>cycloalkyl group or a C<SUB>6 </SUB>to C<SUB>12 </SUB>aromatic group and n is a whole number greater than or equal to one so as to give a functionally of 2 to 6.
