Abstract
This invention provides a composition suitable for use in a reaction zone where aniline is reacted with nitrobenzene to obtain intermediates of 4-aminodiphenylamine comprising a solid support having interior channels with base material employed in the reaction loaded into the channels. The cross-sectional dimensions of the channels are such as to provide a restricted transition state with regard to the reaction and to improve the selectivity of the reaction in favor of the intermediates. The invention also provides a method for loading the base material in the solid support. The invention further provides a process for carrying out the above reaction using the above composition.
