Process for producing bisthiophenolperfluoroalkylidene compound
摘要:
2.2'-bis(3-mercaptophenyl)hexafluoropropane [bisthio-phenol AF] is obtained in good yield by chlorosulfonating 2.2'-bisphenylhexafluoropropane and reducing the thus quantitatively obtained 2,2'-bis(3-chlorosulfonylphenyl)-hexafluoropropane with zinc under acidic conditions and is effectively used as a cross-linking agent for a fluorine-containing elastomer having halogenophenyl groups as cross-linkable groups.
