1-IODO-3,4-DICHLORO-3,4,4-TRIFLUOROBUTYL ACETATE AS INTERMEDIATE PRODUCT FOR PRODUCTION OF 1,1,2-TRIFLUORO-1-BUTENE-4-OL BEING USED IN SYNTHESIS OF POLYFLUORINATED SURFACTANTS FOR COPOLYMERIZATION AND PRODUCTION OF ELECTROLYTES

摘要

FIELD: production of surfactants, processes of copolymerization. SUBSTANCE: desired compound having formula CF₂-CFCl-CH₂-CHJ-OCOCH₃ is prepared by addition reaction of 1,2-dichloro-1,2,2-trifluoriodoethane and vinyl acetate. The process takes place at 25-40 C within 1-3 h in the presence of initiating mixture in aqueous-acetonitrile solution. Sodium dithionate and sodium bicarbonate are used as said initiating mixture. EFFECT: improves quality of desired product.
