氯化亚砜是布洛芬的*初原料,其质量的好坏直接影响布洛芬用中间体氯代丙酰氯的含量和布洛芬的收率。目前,氯化亚砜的生产厂家用沸程法控制其质量。此法专属性差,定量不准;国外采用碱量法、碘量法、银量法测定其含量。

浩瀚色谱（山东）应用技术开发有限公司以热导池为检测器的色谱法,分离好,定量准确，氯化亚砜，硫酰氯，二氧化硫，二氯化硫，一氯化硫得到有效分离，结果满意。

Thionyl chloride is the original raw material of Ibuprofen, and its quality directly affects the content of chloronenenebd propionyl chloride, an intermediate of Ibuprofen, and the yield of Ibuprofen. At present, the manufacturers of Thionyl chloride use boiling range method to control its quality. This method has poor specificity and inaccurate quantification; Its content is determined by alkalimetry, Iodometry and Argentometry abroad.



The chromatographic method of Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. with the thermal conductivity cell as the detector has been well separated and accurately quantified. Thionyl chloride, Sulfuryl chloride, sulfur dioxide, Sulfur dichloride and sulfur monochloride have been effectively separated with satisfactory results.
