Infrared spectra of butylamine adsorbed on a Silica-Alumina catalyst were observed after heating at different temperatures. Heating leads to gradual formation of a series of adsorption bands which can be assigned to ammonia adsorbed on both protonic and aprotonic sites. Moreover, spectra of the gases desorbed at increasing temperatures showed the characteristic frequencies of CH2 = CHCH2CH3. The data thus obtained are discussed with regard to the possibility of using butylamine in obtaining site energy distribution curves.
