disulfides, sulfides and of n-butanethiol in alcohols or aqueous acetonitrile in the presence of oxygen was investigated : the corresponding sulfonic acids are produced in good yields for short alkyl chain compounds, together with smaller amounts of sulfuric and carboxylic acids. In acetonitrile, the influence of added water on the reaction course is evidenced : increased reaction rate and acid yields,
研究了在氧气存在下在醇或乙腈水溶液中脂肪族二硫化物,硫化物和正丁硫醇的短波辐射:短烷基链化合物的相应产率的收率很高,同时硫酸和羧酸的含量也更低酸。在乙腈中,已证明加水对反应过程的影响:反应速度和酸产率提高,控制硫酸的形成。检测到亚磺酸和硫代磺酸盐等中间体,并监测其形成速率。该反应似乎涉及在氧存在下会产生磺酰基自由基的巯基自由基。提出了有关该机制的第一个初步假设。
