Abstract

Adsorption and transformation of allene and propyne over zeolites of different structures and acidities were investigated by means of IR and UV-Vis spectroscopy. The band shifts of v6(CC) and V3(CC) fundamentals of allene and propyne adsorbed on Co2+, Na+ and H+ showed the heterogeneity of adsorption energies of these ions present in zeolites. Formation of alkenyl carbenium ions was proved on acidic zeolites.
