Abstract
The adsorption of different bases (ammonia, n-butylamine, tert-butylam ine, pyridine) in gas phase on solid acidic catalysts (silica-alumina and HY zeolite catalysts and a silica gel) has been studied. By combin ing the adsorption results obtained by calorimetry and thermogravimetr y, the acidic strength distribution of the solids is determined. For t he acidity strength distribution measurement, tertbutylamine has a goo d behaviour and is an alternative base to ammonia.
