Abstract

IR spectra of pyridine adsorbed on zirconium phosphate and zeolite HNaY were studied at temperatures of 400–500 K. Protonation heats of pyridine determined on the OH groups of zirconium phosphate and zeolite HNaY having theυOH at 3640 cm−1, are 65±6.0 and 172±16 kJ/mol, respectively.

Abstract

При температурах 400–500 K исследованы ИК спектры пиридина, адсорбированного на фосфате циркония и цеолите HNaY. Определены ∈еплоты протонизации пиридина на OH группах фосфата циркония (Q=65±6, кдж/моль) и OH группах цеолита HNaY cυOH 3640 цм−1 (Q=172±16 кдж/моль).
