PROCESS FOR THE MANUFACTURE OF FLUOROSURFACTANTS

This invention pertains to a novel process for the manufacture of a perfluorooxycarboxylate of formula (I): RfO-CF2CF2-O-CF2-COOXa (I) wherein Rf is a perfluoro(oxy)alkyl group, and Xa is H, a monovalent metal or an ammonium group of formula NRN4, with RN, equal or different at each occurrence, being H or a C1-6 hydrocarbon group, said process comprising: (A) reacting a perfluorovinylether of formula Rf-O-CF=CF2 with an ethylene glycol derivative selected among ethylene glycol (HO-CH2CH2-OH), glycolic acid (HO-CH2-COOH), glycolaldheyde (HO-CH2-CHO) and protected derivatives thereof, so as to yield the corresponding addition product of formula Rf-O-CFH-CF2-O-CH2-E, with Rf having the same meaning as above detailed, and E being selected among -CH2OH, -COOH and -CHO; (B) optionally protecting functional group E with suitable chemistry; (C) fluorinating said (protected) addition product to yield the corresponding perfluorinated addition product; (D) optionally deprotecting said perfluorinated addition product to yield corresponding acyl fluoride of formula Rf-O-CF2-CF2-O-CF2-C(O)F; (E) hydrolyzing and, optionally, neutralizing, said acyl fluoride for yielding the perfluorooxycarboxylate of formula (I).
