A good yield, high reaction rate process is disclosed for the production of perfluoro(alkyl vinyl ethers). The process involves elimination of halogen, preferably chlorine, from carbon atoms alpha and beta to an ether oxygen in an alpha,beta-dihaloperfluoro ether wherein the alpha,beta-dihaloperfluoro ether is allowed to react with zero valent zinc in a pyrrolidinone solvent. More particularly, the inventive process relates to high yield production of CF2=CFOCF2CF2SO2F from CF2ClCFClOCF2CF2SO2F wherein CF2ClCFClOCF2CF2SO2F is allowed to react with zero valent zinc in the presence of N-methyl-2-pyrrolidinone. |
