Process for the synthesis of mixtures of methane diphenyl diamine and its higher homologues with a controlled isomer distribution |
摘要 |
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 modified zeolite having "shape selectivity". The mixture contains compounds having the following general formula (I): where R represents a hydrogen atom or a C1 to C8 (iso)alkyl group, a C4 to C10 cycloalkyl group or a C6 to C12 aromatic group and n is a whole number greater than or equal to one so as to give a functionality of 2 to 6.
