Summary The influence of the alkali cation exchange in faujasite type zeolites on the zeolite acidity and electronegativity is presented. Correlations between the changes of these parameters and the activity and selectivity of zeolites in the nydrosul-phurization of alcohols are discussed. It was stated that for these processes in which the dissociatively adsorbed H2S takes part, the increase of the zeolite electronegativity causes the decrease in the activity.
