Abstract

Adsorption of methanol-benzene mixtures and heats of immersion have been investigated on the organic derivatives of montmorillonite. The surface of the mineral was modified by n-alkyl pyridinium and dimethyldihexadecyl ammonium ions. In the case of completely exchanged samples the adsorption capacity volumes agree with the interlamellar volumes calculated from X-ray diffraction data rather well. The organophilicity is characterized by the proportion of the nonpolar/polar surfaces. The specific enthalpies of immersion have been measured in methanol, benzene, and their mixtures. The immersion shows endothermic-exothermic or endothermic heat effects.
