Title (EN) METHOD OF MAKING FLUORINATED VINYL ETHERS
(FR) PROCEDE DE PREPARATION D'ETHERS VINYLIQUES FLUORES
Abstract:
(EN) The present application provides a process to produce fluorinated vinyl ether by reacting a 2-alkoxypropionyl fluoride with a metal carbonate under anhydrous conditions in a stirred bed reactor at a temperature above the decarboxylation temperature of an intermediate carboxylate to produce a fluorinated vinyl ether. The process is carried out in the absence of solvent. With the process described, fluorinated vinyl ether of a high purity can be obtained in a high throughput manner.
(FR) L'invention concerne un procédé de production d'éther vinylique fluoré consistant à faire régir du 2-alcoxypropionyl fluorure avec un carbonate métallique, dans des conditions anhydres, dans un réacteur à lits agités et à une température supérieure à celle de la décarboxylation d'un carboxylate intermédiaire, aux fins de production d'un éther vinylique fluoré. Le procédé est effectué en l'absence de solvant. Un éther vinylique fluoré très pur peut être obtenu à un rendement élevé grâce au procédé selon l'invention.
