-
Patent number: 10745348Abstract: A process for preparing diaryl sulfones, such as 4,4?-dichlorodiphenylsulfone is disclosed. The process comprises contacting an aryl compound with sulfur trioxide to provide a benzene sulfonic acid. The benzene sulfonic acid is coupled to additional aryl compound in the presence of a catalyst. During the coupling step, the additional aryl compound is continuously added while water is removed.Type: GrantFiled: June 9, 2016Date of Patent: August 18, 2020Assignee: Vertellus Holdings LLCInventors: Ramiah Murugan, David A. Hay
