Реферат:
Interaction of naphthalene, α-methylnaphthalene, and hexamethylbenzene with OH groups of SiO2, HNaY and H-ZSM-5 zeolites was studied by IR spectroscopy. The results are compared with data obtained for other types of organic bases. Specificity in the generation of H-complexes of olefins, arenes, naphthalenes, N- and O-bases with Brönsted surface sites was elucidated. Each type of base appears to have its particular correlation of (PAa-PAb) and the shift of ΔυOH band in H-complexes. It has been found that if (PAa-PAb) is less than 85±5 kcal/mol, the formation of ion pairs is thermodynamically more favorable than that of H-complexes for all types of organic compounds.
