三氧化乙烯硫脲合成

his paper mainly introduce the reaction path of hydrogen peroxide oxidation of ethylene thiourea, and a new method that oxidize the ethylenethiourea dioxide to synthesize the ethylenethiourea trioxide was announced. In this way, water was acted as the reaction medium for synthesizing the ethylenethiourea. The production was analysised by mp, HPLC and NMR, and the production was the ethylenethiourea trioxide. Moreover, It was found that ,when the ethyelenthioure dioxide was 15g, the optimum mass of water was 20g, sulfuric acid was 2mL, and the reaction temperature was 40~60℃. However, when the temperature is not rise, the reaction is completed. Finally, analysis of the reason for deterioration of the product at room temperature was figured out, and the method for preserving the product was given.
