Study of addition reaction among fluorosulfonyl-difluoroacetyl fluoride, hexafluoropropyl epoxide and hexafluoropropylene

Abstract

The reaction among FO2SCF2COF, HFPO and HFP in the presence of fluorine ion has been studied. It was found that, at the beginning of the reaction, a period is influenced by the solvent quantity and the temperature. The formation of (CF3)2CFCOCF(CF3)OCF2CF2SO2F took place rapidly only when the temperature was above 5`C in the presence of emulsified catalyst. ^1^9F NMR measurements showed that the reactivity of fluorine ion towards FO2SCF2COF, HFPO and HFP proceeded probably in the following sequence: FO2SCF2COF>HFPO>HFP

Key words: PERFLUOROPROPENE, METHYLOXIRANE P, ORGANO FLUORINE COMPOUNDS, ACYL FLUORIDES, ADDITION REACTION, SULFONYL GROUP, ACETIC ACID P
