| Abstract: | Differential heats of benzene adsorption at 293 K on Mg2+, Ca2+, Sr2+, Ba2+ metakaolinites at surface coverages of  =0.2 have been measured in a Calvet microcalorimeter. An inverse dependence of benzene and cuene adsorption heats on monocationic metakaolinites has been revealed. The presence of two types of adsorption centers is predicted.
