Abstract
The methodology developed gas-phase oxidation of various hydrocarbons and their derivatives, their reaction with coherentsynchronized decomposition reaction of hydrogen peroxide and nitrous oxide, which generate in an environment highly intermediates - O, OH, HO·2 radicals, yielded a number of practically important compounds, with relatively high yields and selectivity at atmospheric pressure without using special catalysts. This methodology was first used for the selective oxidation of nitrogencontaining heterocyclic compounds. As a model reaction used coherent-synchronized oxidation of pyridine (P) in the temperature range: Hydrogen peroxide (300-5000C) and nitric oxide (530-6200C). As a result of experimental studies the scientific bases of synthesis of 2,2-oksidipyridyl are designed by oxidation of pyridine with hydrogen peroxide. This way the selective production of 2,2-oksydipyridyl (fig.1) is free from a number of disadvantages inherent in the known methods of catalytic oxidation ofpyridine. Substantial interest undoubtedly presents practical important synthesis of pyridine bases by the "green oxidant" - nitrous oxide by free-radically mechanism. Experimental studies have shown that in the temperature range 530-6200C pyridine occurs selective oxidation reaction with nitrous oxide to form 2,2-dipyridyl (23.0 wt.%) and 2,3-dipyridyl (25.4 wt%) [4,5]. Kinetic curves presented in fig. 1 and 2 clearly show us a unique opportunity to obtain valuable practical pyridine bases, according to the simplified technology.
