CA 2687425

A method for producing aniline or toluenediamine is disclosed which comprises forming a dispersion comprising hydrogen gas bubbles dispersed in a liquid medium comprising either nitrobenzene or dinitrotoluene, wherein the hydrogen gas bubbles have a mean diameter less than 1 micron; and subjecting the dispersion to hydrogenation reaction promoting conditions comprising pressure less than about 600 kPa and temperature less than about 200°C, whereby at least a portion of the nitrobenzene or dinitrotoluene is hydrogenated to form aniline or toluenediamine, respectively. A system for carrying out the method is also disclosed.

L'invention concerne un procédé de production d'aniline ou de toluènediamine qui comprend la formation d'une dispersion comprenant des bulles d'hydrogène gazeux dispersées dans un milieu liquide comprenant soit du nitrobenzène soit du dinitrotoluène, où les bulles d'hydrogène gazeux ont un diamètre moyen inférieur à 1 micron ; et la soumission de la dispersion à des conditions favorisant une réaction d'hydrogénation comprenant une pression inférieure à environ 600 kPa et une température inférieure à environ 200 °C, moyennant quoi au moins une partie du nitrobenzène ou du dinitrotoluène est hydrogénée pour former une aniline ou toluènediamine, respectivement. Un système pour réaliser le procédé est également décrit.
