Abstract
F-3-Methylbutene-1 has been oxidized using oxygen and ultraviolet radiation to form poly(carbonyl fluoride) oligomers. The formation of fluoroformate terminated material is insignificant. This is in sharp contrast to the products derived from the prior art oxidation of F-propene (HFP) in which up to 60% fluoroformate terminated material was produced. F-Ethylene (TFE) can be added to the F-3-methylbutene-1 reaction gas stream without adversely affecting the product composition. The fluoride oligomers, after addition of one unit of hexafluoropropylene oxide, can be converted to s-triazines which have excellent properties as hydrualic fluids.
