title: A dramatic improvement of epoxide selectivity of [Ti,Al]-beta by ion-exchange with quaternary ammonium salts.
abstract: Ion-exchange of [Ti,Al]-beta with quaternary ammonium acetates greatly enhances the epoxide selectivity in the oxidation of alkenes with hydrogen peroxide; this is due to the selective poisoning of the acid sites without suppressing the oxidation activity of Ti sites.
