Abstract
Acidity measurements using Hammett indicators have been applied to macroporous sulfonic acid ion-exchange resins in nonpolar media. The acidity was varied by partial ion-exchange. It has been proven that the adsorption of the indicator molecules is reversible in the case of a thermally pretreated resin. From the measurement of the adsorption data, the ionization ratio of the indicators can be calculated and correlated to the reactivity in the alkylation of benzene with propene and to the degree of ion-exchange. Using these correlations, a relative acidity scale can be defined. The accessibility of acid groups in different solvents must be determined as a prerequisite for the application of the theory developed in this study.
