PRODUCTION OF FLUORINE-CONTAINING VINYL ETHER

Title:

PRODUCTION OF FLUORINE-CONTAINING VINYL ETHER

Document Type and Number:

Japanese Patent JP3722530

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To produce a fluorine-containing vinyl ethane from an alkoxide compound and tetrafluoroethlene in high yield.
SOLUTION: A fluorine-containing vinyl expressed by the formula RfCH2 OCF=CF2 is produced by reacting an alkoxide compound expressed e.g. by the formula RfCH2OM (Rf is a fluorinated hydrocarbon group expressed by CaHbFcXd (X is a halogen atom; (a), (b), (c) and (d) are each an linteger of ≥0; b+c+d≤2a+1);M is an alkali metal) with ≥3 times mol if tetraflioroethylene.
