Abstract

The invention provides an analytical test method of perfluorosulfonyl fluoride alkene ether, which comprises the following steps: mixing a perfluorosulfonyl fluoride alkene ether solution with a bromination reagent, reacting, washing the reaction product, and carrying out gas chromatographic analysis. According to the method, after the perfluorosulfonyl fluoride alkene ether is pretreated, the product purity can be quantitatively analyzed by adopting gas chromatography, the result is reliable, the operation is simple, and the method can be used for guiding the research and production of the perfluorosulfonyl fluoride alkene ether.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection, and in particular relates to an analysis and test method of perfluorosulfonyl fluoride alkenyl ether. Background technique [0002] Perfluorosulfonyl fluoride alkenyl ether is an important fluorine-containing intermediate, and its main function is to introduce functional sulfonic acid group chains into polymers. Perfluorosulfonyl fluoride alkenyl ether is the core raw material for the synthesis of perfluorosulfonic acid ion exchange resins. Perfluorosulfonic acid ion exchange resins are mainly used to synthesize perfluorosulfonic acid ion exchange membranes, and can also be used as super acid catalysts. The perfluorosulfonic acid ion exchange membrane was made of perfluorosulfonic acid ion exchange membrane by the chemical name of perfluoro(3,6-dioxa-4-methyl-7-octene)sulfonyl fluoride from DuPont of the United States. It was first developed and adopted in the 1970s. Widely used ...
