| titleOfInvention | Method for producing a composition comprising a single-terminal carboxyl group-containing perfluoropolyether compound |
| abstract | The present invention provides a method for efficiently producing a composition containing a single-terminal carboxyl group-containing perfluoropolyether compound at a high concentration using only a fluorine-based solvent that is not an acidic polar compound. The present invention includes a perfluoropolyether compound containing a single-terminal carboxyl group represented by the general formula (2): R1-Rf-R2COOH and having a number average molecular weight of 1,000 to 8,000, and the general formula (3): The composition may contain a perfluoropolyether compound containing carboxyl groups at both ends represented by HOOCR2-Rf-R2COOH, and the ratio of the perfluoropolyether compound of the general formula (2) is 70 mol% or more. A method for producing a composition, further comprising the step of obtaining a mixture of perfluoropolyether compounds by fluorinating some of the carboxyl groups of the carboxyl group-containing perfluoropolyether compound of the general formula (3). Method. [Selection figure] None |
