Abstract

The kinetics and mechanism of the decomposition of thiourea dioxide in an aqueous alkaline solution under aerobic and anaerobic conditions are established. It is discovered that along with the decomposition of thiourea dioxide molecules with C–S bond cleavage and the subsequent formation of sulfoxyl acid anions, there is a reversible stage of the formation of thiourea and peroxide anions. The rate constants of the indicated stages are determined via mathematical modeling using the experimental data.

碱性水溶液中好氧和厌氧条件下二氧化硫脲的分解

摘要

建立了好氧和厌氧条件下碱性水溶液中二氧化硫脲分解的动力学和机理。已发现,随着硫脲二氧化物分子因C–S键断裂而分解以及随后形成的亚硫羟酸阴离子,硫脲和过氧化物阴离子的形成过程是可逆的。指示阶段的速率常数是使用实验数据通过数学建模确定的。
