摘要
介绍了用二苯醚为原料,经浓硫酸磺化、再与三氯氧磷反应制备4,4′-氧化双苯磺酰氯的方法。与二苯醚直接同氯磺酸反应的制法相比,产率高、产品纯,并易于工业化。
A method for synthesizing of 4,4'-Oxybis (phenylsulfonylchloride) by sulfonating the raw material diphenyl ether with concentrated sulf uric acid, and then by reacting with phosphorus oxychloride was studied. Compared with the method of direct reaction of diphenyl ether with chlorsufonic acid, the new method has some advantages such as high yield, high purity of product and being easy to industrialize.
