FIELD: industrial organic synthesis.
SUBSTANCE: invention relates to composition suitable for use in reaction zone wherein aniline is brought into contact with nitrobenzene to produce 4-aminodiphenylamine synthesis intermediates, which composition contains zeolite having internal channels with a base introduced therein to take part in above reaction. Dimensions of cross-section of channels is such that a limited reaction transition state is ensured thereby improving selectivity of reaction with regard to desired intermediates. Invention also related to the title process using above defined composition.
EFFECT: improved selectivity of 4-aminodiphenylamine intermediates production.
