Method for production of perfluoro-(N-vinylamine) compounds

摘要

A perfluoro-(N-vinylamine) compound containing a >NCF=CF2 group is produced from a perfluoro-compound containing a group of the general formula: <IMAGE> (wherein X stands for a fluorine atom or a -OM group having an alkali or alkaline earth metal ion for M) and having connected to the group of the general formula a perfluoro-alkyl group having a total of 2 to 6 carbon atoms contained in the main carbon chain thereof by heating the perfluoro-compound at a temperature in the range of 100 DEG C. to 500 DEG C. thereby effecting conversion of the group of the foregoing general formula into the aforementioned >NCF=CF2 group.
