- 1. A process for producing a fluorovinyl ether having the formula:
- XR.sub.f CF.sub.2 OCF.dbd.CF.sub.2 (I)
- wherein X represents --H, --Cl, --Br, --F, --CO.sub.2 R, --CONRR', --SO.sub.2 F, ##STR9## or --COF, and R represents a C.sub.1 -C.sub.10 alkyl group; R' represents --H or a C.sub.1 -C.sub.10 alkyl group; R.sub.f represents a C.sub.1 -C.sub.20 bifunctional perfluoro-containing group which can have one or more ether bonds, which comprises reacting an iodine-containing ether having the formula:
- XR.sub.f CF.sub.2 OCF.sub.2 CF.sub.2 I (II)
- wherein X and R.sub.f are as defined above, in the presence of a particulate, metallic catalytic component selected from the group consisting of Zn-Cu, Zn-Cd, Zn-Pd, Zn-Hg;
- wherein the iodine-containing ether (II) is reacted with said catalytic component in an inert polar aprotic organic solvent selected from the group consisting of benzonitrile, .alpha.-naphthonitrile, .beta.-naphthonitrile, diphenyl ether, and mixtures thereof.
- 2. A process for producing a fluorovinyl ether according to claim 1 wherein said reaction of said ether of formula II with said catalytic component yields an intermediate fluoro-organometallic compound which is then thermally reacted to form said fluorovinyl ether (I).
- 3. A process for producing a fluorovinyl ether according to claim 2 wherein the thermal reaction of the resulting fluoro-organometallic compound is carried out after the removal of the organic solvent.
- 4. A process for producing a fluorovinyl ether according to claim 2 wherein the production of the fluoro-organometallic compound and the thermal reaction thereof are carried out by one step process.
- 5. A process for producing a fluorovinyl ether according to claim 2 wherein the reaction for producing the fluoro-organometallic compound is carried out at from -50.degree. C. to +200.degree. C.
- 6. A process for producing a fluorovinyl ether according to claim 2 or 3 wherein the thermal reaction of the fluoro-organometallic compound is carried out at from 100.degree. C. to 300.degree. C.
- 7. A process of producing a fluorovinyl ether having the formula:
- XR.sub.f CF.sub.2 OCF.dbd.CF.sub.2 (I)
- wherein X represents --H, --Cl, --Br, --F, --CO.sub.2 R, --CONRR', --SO.sub.2 F, ##STR10## or --COF, and R represents a C.sub.1 -C.sub.10 alkyl group; R' represents --H or a C.sub.1 -C.sub.10 alkyl group; R.sub.f represents a C.sub.1 -C.sub.20 bifunctional perfluoro-containing group which can have one or more ether bonds, which comprises reacting an iodine-containing ether having the formula:
- XR.sub.f CF.sub.2 OCF.sub.2 --CF.sub.2 I (I)
- wherein X and R.sub.f are as defined above, in the presence of a particulate, metallic catalytic component selected from the group consisting of Zn-Cu, Zn-Cd, Zn-Pb, Zn-Hg;
- wherein the iodine-containing ether (II) is converted into the fluorovinyl ether (I) by a vapor phase catalytic reaction in the presence of the catalytic component.
- 8. A process for producing a fluorovinyl ether according to claim 7 wherein the vapor phase catalytic reaction is carried out at from 150.degree. C. to 450.degree. C.
- 9. A process for producing a fluorovinyl ether according to claim 7 wherein the reaction is carried out by diluting the iodine-containing ether (II) with an inert gas.
- 10. A process for producing a fluorovinyl ether according to claim 7 wherein the catalytic contact time of the iodine-containing ether (II) with the catalytic component is from 0.1 to 600 seconds.
- 11. A process for producing a fluorovinyl ether according to claim 7 wherein a fixed bed reactor, a transferring bed reactor or a fluidized bed reactor is used as the reactor for the vapor phase catalytic reaction.
- 12. A process for producing a fluorovinyl ether according to claim 9 wherein the vapor phase catalytic reaction is carried out at a ratio of inert gas to iodine-containing ether (II) of from 70:30 to 99:1.
