Identification of different carbenium ion intermediates in zeolites with identical chabazite topology via13C–13C through-bond NMR correlations

Abstract

¹³ C–¹³C through-bond NMR correlation experiments reveal the stabilization of different carbenium ion intermediates in two zeolites possessing identical CHA topology (H-SAPO-34 and H-SSZ-13) during the methanol to olefins reaction.
