The Study of Synergism of Acid and Base Centers in Catalytic Dehydration for Propanol-[2]

Abstract

Abstract: Based on the experimental results of IRdetection of the absorbed species and effect of acid-base strength on the catalytic properties,it is shown that the activity and selectivity for catalytic dehydration of propanol-[2] are high at an appropriate acid, and basic strength and a H_0,max value. The existance of an adsorbed species (-CH₂) on catalyst surface verified by IRmeasurement, means that the reaction takes place by interactions between OHgroups of propanol-[2] and acid centers of the given catalyst surface and between Hgroups ofβ-Cin the reactant and base centers of catalyst.It is possible that the acid-base center synergism enables the given reaction to taske place.

Key words: Acidity, Basicity, Acid strength, Base strength, Synergism
