摘要:
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.
