氯化亚砜生产工艺技术特点分析

Analysis of the Technical Feature of Thionyl Chloride Manufacturing Technique

氯化亚砜生产工艺技术中,因工艺方法不同,可以分为氯磺酸法、联产法、二氧化硫气相法、三氧化硫气相法。以上技术在原料选择、反应控制等方面要求各不相同,通过对以上工艺进行比较,选出更优工艺方案。

For the manufacturing technique of thionyl chloride, due to the difference of technical methods, it can be divided into chlorosulfonic acid method, combined-production method, sulfur dioxide gas phase method and sulfur trioxide gas phase method. The above techniques are different in the aspects of raw materials selection and reaction control etc., besides, through taking comparison of the above techniques to select the better technical plan.
