Abstract

The interaction of pyridine with the surface of Y-type decationized zeolite has been studied by IR spectroscopy over a wide temperature range. It has been shown that the first step of the transfer of a hydroxyl proton to a base is the formation of a strong hydrogen bond. The protonated pyridine exists in free and hydrogen-bonded forms.

Abstract

Методом ИК спектроскопии в широком интервале температур исследовано взаимодействие пиридина с повэрхностью декатионированного цеолита типа У. Показано, что первым этапом перехода протона гидроксильных групп к основанию является образование сильной водородной связи. Протонизированный пиридин существует в свободной и водородносвязанной формах.
