【Abstract】 Performances,sulfonation process and applications of the concentrated sulfuric acid, chlorosulfonic acid,sulfur trioxide,amino-sulfonicacid,sulfites and other sulfonating agents were overviewed. Advantages and disadvantages of these sulfonating agents were compared as well as development trend. Sulfur trioxide as sulfonating agent of various sulfonation processes and current research progress were discussed. It pointed out that the sulfur trioxide sulfonation will widely used as it is a sulfonation agent of superior performance and green environmental protection. Sulfur trioxide sulfonation has a wide range of development potential in the petroleum and fine chemical industry at present,and it needs to do more research at the two aspects of equipments and processes in order to solve the current technical difficulty.更多还原
