Résumé

Des montmorillonites cuivriques ont été exposées à des vapeurs de benzène, au cours de cycles de déshydratation, adsorption, désorption de l'excès et réhydratation. La fixation du benzène et sa transformation dans les espaces interfoliaires ont été suivies au moyen d'analyses thermogravimétriques, radiocristallographiques et spectrophotométriques infrarouges. Celles-ci ont permis de mettre en évidence deux réactions, correspondant l'une à l'adsorption d'une molécule de benzène par ion Cu2+, l'autre à trois molécules de benzène. Ce dernier se polymérise dans les espaces interfoliaires avec formation tout d'abord de poly (p-phénylène) puis d'un composé qui pourrait s'apparenter à du graphite.

Abstract

Abstract

Cu-montmorillonites were exposed to benzene vapours during cycles of dehydration, adsorption desorption of the excess reagent and rehydration. The fixation of benzene and its changes in the interlayer spaces were studied by means of thermogravimetry and X-ray diffraction techniques and infrared spectrophotometry analysis. Two reactions were demonstrated, one corresponding to the adsorption of one benzene molecule on the Cu2+ ion, and the other to the uptake of three benzene molecules. In the latter case, benzene polymerizes in the interlayer spaces, resulting in the formation of poly (p-phenylene) in the first stage and, finally, of a compound related to graphite.
