Patent

CA 2413409

This invention provides a composition suitable for use in a reaction zone where aniline is reacted with nitrobenzene to obtain intermediates of 4-amino- diphenylamine comprising a solide 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.

L'invention concerne une composition pouvant être utilisée dans une zone de réaction dans laquelle on fait réagir de l'aniline avec du nitrobenzène pour obtenir des produits intermédiaires de 4-amino-diphénylamine. Cette zone comprend un support solide pourvu de canaux intérieurs, le matériau de base utilisé pour la réaction étant chargé dans ces canaux. Les dimensions transversales des canaux permettent, d'une part, d'obtenir un état de transition restreint pour ce qui est de la réaction et, d'autre part, d'améliorer la sélectivité de la réaction en favorisant les intermédiaires. L'invention concerne également un procédé permettant de charger le matériau de base dans le support solide, et un procédé permettant de réaliser cette réaction à l'aide de la composition susmentionnée.
