- Continuous-flow step-economical synthesis of thiuram disulfidesviavisible-light photocatalytic aerobic oxidation
-
A continuous-flow photocatalytic synthesis of the industrially important thiuram disulfides has been developed, utilizing O2as the oxidant and Eosin Y as the photoredox catalyst. This highly atom- and step-economical method features much reduced reaction time as well as excellent product yield and purity, making it a sustainable and potentially scalable process for industrial production.

- Synthesis process of N, N'-dialkyl-N, N'-diphenylthiuram disulfide
-
The invention relates to a synthesis process of N, N '-dialkyl-N, N'-diphenylthiuram disulfide. The conversion rate of raw materials is improved, the product yield reaches 98% or above and the productpurity reaches 98.5% or above through the measures of using a preferred catalyst, adding initial raw materials at a time, controlling side reactions through low-temperature oxidation and the like. According to the process, inorganic salt byproducts are not generated, the feeding operation is simple and convenient, the reaction is efficient and thorough, and meanwhile, a high-purity product is obtained.
