GAS-PHASE OXIDATION OF 2-PICOLINE BY “GREEN OXIDIZERS” H2O2 AND N2O

Abstract

This communication presents the results of studies of coherently synchronized reactions of 2-picoline oxidation with hydrogen peroxide and nitrous oxide (I) in the gas phase. Optimal conditions for obtaining target products in these reactions are revealed. The influence of the process parameters on the value of the determinant in the reactions: dealcodimerization of 2-picoline with hydrogen peroxide and dimerization of 2-picoline with nitrous oxide (I) is shown. Calculated in the reaction of deal-codimerization of 2-picoline with hydrogen peroxide, the determinant of chemical conjugation has a value of D = 0.17 under optimal conditions, which indicates the induced character of dealcodimerization of 2-picoline. Based on this value, a quantitative assessment of the influence of the primary reaction (decomposition of hydrogen peroxide) on the secondary one (dealcodimerization of 2-picoline) was given. In the reaction of dimerization of 2-picoline with nitrous oxide (I), the chemical conjugation determinant has, under optimal conditions, a value of D = 0.54, which, according to the chemical interference scale, is in the region of chemical conjugation, when the primary reaction (the decomposition of nitrous oxide (I)) accelerates the secondary reaction (dimerization of 2-picoline)
