ROLE OF THEORY ACIDS AND BASES IN THE FORMING CONCEPTS OF THE MECHANISM CATALYTIC OXIDATION AND OXIDATIVE AMMONOLYSIS

Abstract

Experimental data of oxidation and oxidative ammonolysis the isomeric methylpyridines in the presence of vanadium oxide catalysts, it was found that the reactivity of substrates increases in the following sequence: 3-methylpyridine < 2-methylpyridine < 4-methylpyridine. The obtained experimental results of relative reactivity of initial compounds were interpreted by the theory of acids and bases. It was shown that among the isomeric methylpyridines, increase of basicity which influence to adsorpting ability in the same order as the basicity and the CH-acidity of substrates calculated using non-empirical quantumchemical methods.
