, (2008/06/13)
A novel bifunctional vinyl ether compound having an aromatic ring, represented by the following general formula: STR1 where X is a halogen atom and n is an integer of 1 to 5, effective as a copolymer component for fluorine-containing elastomers is produced by adding a chlorine atom or a bromine atom (Y) to CF2 =CFO(CF2)nCOOR, where R is a lower alkyl group, then subjecting the resulting CF2 YCFYO(CF2)nCOOR to hydrolysis and acid chloridation, followed by reaction with monohalogenobenzene, reaction with SF4 to convert --CO-- to --CF2 --, and dechlorination or debromination, or by subjecting CF2 =CFO (CF2)nCOOR to hydrolysis and acid chloridation, followed by reaction with monohalogenobenzene and reaction with SF, to convert --CO-- to --CF2 --.

In an aqueous medium in the presence of potassium persulfate or hydrogen peroxide methyl perfluoro-5-oxa-6-heptenoate is converted into perfluorosuccinic acid.Study of the reaction and the structure of the intermediate and final compounds made it possible to discover a multistage scheme for the transformation of methyl perfluoro-5-oxa-6-heptenoate with oxidation at the double bond followed by hydrolysis of the terminal groups.The transformation rate of methyl perfluoro-5-oxa-6-heptenoate at 60 deg C was determined.
