Perfluoroalkylbenzenesulfonyl chlorides, perfluoroalkylnaphthalenesulfonyl chlorides, and their metal salts
摘要:
Meta-perfluoro-n-alkylbenzenesulfonyl chlorides and 1-perfluoro-n-alkylnaphthalene-5-sulfonyl chlorides were synthesized from the corresponding perfluoroalkylaromatics in good yield by the action of chlorosulfonic acid. From the acid chlorides, salts (RSO3M, where M = Li, K, Ba, Zn and Al) were prepared and their TGA curves obtained. With the exception of the aluminum salts, the materials were stable to at least 350-degrees-C. All the salts were essentially insoluble in Cl(CFClCF2)3-4Cl.
