摘要
介绍了无机精细化工产品氯化亚砜在医药、农药等工业领域的应用及其在有机合成反应、成环 (或闭环 )反应中的应用开发现状 ;评述了氯磺酸法、三氧化硫法、二氧化硫法、联产法等氯化亚砜合成方法及其采用这些合成方法的生产企业情况 ;分析了氯化亚砜国内生产、需求、进出口情况。建议尽快淘汰落后的氯磺酸法工艺 ,新建装置应考虑原料来源、规模效益等因素并采用先进工艺技术。
Applications of thionyl chloride in pharmaceutical and pesticide sectors and application developments in organic synthesis reaction and ring formation reaction are introduced. Synthesis methods of thionyl chloride such as HSO 3Cl method, SO 2 method, SO 3 method, co production method and enterprises adopting above methods are evaluated. The domestic production, demand, import and export of thionyl chloride are analyzed. It is suggested that backward HSO 3Cl method should be eliminated and new plants should adopt advanced technologies. Factors such as feedstock source and scale effect should be considered when new plants are being built.
