Title:
MIXTURE OF POLYFLUOROALKENE CARBOXYLIC ACID OR SALT THEREOF AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/021441
Kind Code:
A1
Abstract:
A mixture of a polyfluoralkene carboxylic acid indicated by general formulas CnF2n+1CH=CF(CF2CF2)mCF2COOM and Cn-1F2n-1CF=CHCF2(CF2CF2)mCF2COOM (M indicates a hydrogen atom, an ammonium salt, an organic amine salt, or an alkali metal, n is an integer 1-6, and m is an integer 0-2) or a salt thereof. This mixture of the polyfluoroalkene carboxylic acid or a salt thereof is obtained by causing a dehydrofluorination reaction by the polyfluoroalkene carboxylic acid indicated by general formula CnF2n+1(CH2CF2)(CF2CF2)mCF2COOH, in the presence of a nitrogen-containing heterocyclic compound catalyst, has a low critical micelle concentration, has a low surface tension at that time, and is effectively used as a surfactant during fluorine-containing monomer polymerization.
