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)

“绿色氧化剂”h2o2和n2o气相氧化2-吡啶

本文介绍了2-吡啶与过氧化氢和一氧化二氮(I)在气相中同步氧化反应的研究结果。揭示了在这些反应中获得目标产物的最佳条件。研究了2-吡啶与过氧化氢脱醇二聚化反应和2-吡啶与氧化亚氮二聚化反应中工艺参数对决定因素值的影响。通过对2-吡啶与过氧化氢共聚反应的计算，在最优条件下，化学偶联的决定因素D = 0.17，表明了2-吡啶脱醇二聚的诱导性质。在此基础上，定量评价了一次反应(过氧化氢分解)对二次反应(2-吡啶脱醇二聚化)的影响。在2-吡啶与氧化亚氮(I)二聚化反应中，在最优条件下，当一次反应(氧化亚氮(I)分解)加速二次反应(2-吡啶二聚化)时，化学偶联行列式D = 0.54，根据化学干扰标度，该行列式处于化学偶联区域。
