摘要：
The interfering kinetics of the synchronous reactions of hydrogen peroxide decomposition and the oxidation of pyridine derivatives have been studied experimentally. The regions of the selective oxidation of the C pyridine derivatives have been found, and the optimal conditions for the production of 4-vinylpyridine, 4vinylpyridine N-monoxide, 2,2-dipyridyl, and pyridine have been determined. The most probable synchronization mechanism is suggested for hydrogen peroxide decomposition and the free-radical chain oxidation of pyridine derivatives. The HO2center dot radical plays the key role in this mechanism. The activation energies are calculated 2 for the elementary steps of 4-ethylpyridine dehydrogenation.
