Resumo: The relative acid strength of lanthanum catalysts supported on paligorskyte was determined by thermodesorption of n-butylamine and infrared absorption spectroscopy. The results indicated that the desorption reaction took place in four temperature ranges. The catalyst containing 2% lanthanum particularly showed a considerable number of acid sites probably as a result of the relatively high specific area of the material
