摘要

摘要研究了热等离子体脉冲辐射活化对苯二酚与水的相互作用。在对苯二酚与辐照期间积累在水中的产物(亚硝酸和过氧亚硝酸)的反应中，对苯二酚发生链式氧化生成苯醌。分析了链式氧化的机理。研究了电晕放电冷等离子体(OH•自由基)对对苯二酚的分解。电晕放电作用下不产生苯醌;对苯二酚立即分解成更小的分子。所考虑的对苯二酚氧化过程可用于产生基于对苯二酚↔对苯二酚对的氢元素。

Chain Oxidation of Hydroquinone by Water Activated by Pulsed Hot-Plasma Radiation

Abstract

The interaction of hydroquinone with water activated by hot-plasma pulsed radiation has been studied. In the reactions of hydroquinone with products accumulated in water during irradiation (nitrous and peroxynitrous acids), hydroquinone undergoes chain oxidation to benzoquinone. The mechanism of chain oxidation is analyzed. The decomposition of hydroquinone by corona discharge cold plasma (OH^• radicals) was studied. Benzoquinone is not produced by the action of corona discharge; hydroquinone immediately decomposes into smaller molecules. The hydroquinone oxidation process considered can be used to create hydrogen elements based on the hydroquinone ↔ benzoquinone couple.

期刊介绍： High Energy Chemistry publishes original articles, reviews, and short communications on molecular and supramolecular photochemistry, photobiology, radiation chemistry, plasma chemistry, chemistry of nanosized systems, chemistry of new atoms, processes and materials for optical information systems and other areas of high energy chemistry. It publishes theoretical and experimental studies in all areas of high energy chemistry, such as the interaction of high-energy particles with matter, the nature and reactivity of short-lived species induced by the action of particle and electromagnetic radiation or hot atoms on substances in their gaseous and condensed states, and chemical processes initiated in organic and inorganic systems by high-energy radiation.
