Abstract

IR-spectroscopic studies indicate that toluene molecules are adsorbed on coordinatively unsaturated surface aluminium ions and hydroxy groups. The formation of benzoates is observed only at 723 K. A reason for the absence of dissociative adsorption of toluene with CH bond cleavage of the methyl group is discussed.

Abstract

Методом ИК-спектроскопии показано, что молекулы толуола стабилизируются на координационно ненасьпценных ионах алюминия поверхности и гидроксильных группах. Образование бензоатных структур зафиксировано лишь при 723 K. Обсуждается причина отсутствия диссоциативиой адсорбции толуола с разрывом CH связи метильной группы.
