工业副产物硒的氧化

在化学反应中，二氧化硒作为温和的氧化剂，可以将羟基、甲基等基团氧化为醛基，而本身被还原为硒，成为废弃物。以合成反应中生成的硒为原料，用浓硝酸和浓硫酸的混合物进行氧化反应，使其氧化为可以重复使用的二氧化硒，反应收率为94％，并用滴定法测定其含量为96％，符合工业化生产的要求。

Oxidation of By-Production Selenium in Synthesis Reaction

In chemical reaction, dioxide selenium, as gentle oxidant ,can oxidized some group,such as hydroxide ,methyl to aldehyde group, and was reduced to selenium itself. Selenium produced in synthesis reaction was oxidized to recyclable dioxide selenium by the mixture of concentrated nitric acid and sulfuric acid. The reaction yield was 94%. The content of dioxide selenium produced was 96% and fit to the need of industry produce.
