    • 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.
    • 使用氧和紫外线辐射使F-3-甲基丁烯-1氧化形成聚(碳酰氟)低聚物。 氟甲酸酯封端材料的形成是微不足道的。 这与来自现有技术的F-丙烯(HFP)的氧化产物产生鲜明的对比,其中产生高达60%的氟甲酸酯封端的材料。 可以将F-乙烯(TFE)加入到F-3-甲基丁烯-1反应气流中,而不会不利地影响产物组成。 加入一单位的六氟环氧丙烷之后,氟化物低聚物可以转化为具有优异性能的水溶液的s-三嗪。
