Abstract: The sorption of n-butylamine (n-BA) on ferric exchanged Y zeolite catalysts has been studied. Freundlich equation is applicable to the sorption data of ferric-exchanged zeolites. The amount of n-BA retained on zeolites under vacuum at different temperatures has been reported which predicts the trend in the acidic strength. FeNaY (46) zeolite shows maximum number of strong acidic centres. The adsorption data for FeNaY zeolite, activated at 500°C, show migration of ferric ions from supercages to sodalite cages or hexagonal prisms, thereby lowering the acidity of zeolite. The isosteric heats of sorption of n-BA on FeNaY zeolites have been determined which support the heterogeneity of surface and migration of ferric ions after heating at 500°C.
