Abstract
Changes in the acid strength of synthetic H, Na−MOR ion exchanged to different degrees have been characterized by IR spectroscopy. A distinct shift in the frequency of the ∼3600 cm−1 band was observed increasing the degree of ion exchange. The accessibility of these sites is also revealed.
Abstract
Изменения в кислой силе синтетигеских ионов H,Na-MOR обмененных до различной степени, характеризовали с помощью ИК спектроскопии. При увеличении ионного обмена наблюдался явный сдвиг полосы при ∼3600 cm−1. Обсуждается также доступность этих центров.
