Synthesis of New High Molecular Weight Cyclic Fluorocarbons and Highly Branched Fluorocarbons Such as Perfluoro-3,3-Diethylpentane

摘要

Perfluoromethylcyclooctane, perfluorocyclodecane, perfluorocyclododecane, perfluorocyclotetradecane, perfluoro-3,3-diethylpentane, perfluoro-3-ethyl-pentane and perfluoro-4-propylheptane have been synthesized by carefully controlled elemental fluorination. The unusually melting points. 19F, 13C, (19 F) (19F decoupled) NMR and mass spectra are discussed. Preliminary transpiration rates in mice following intraperitioneal injection of neat liquid and emulsions are described in brief. A novel guideline of preparation of thermally, chemically stable perfluorinated fluids is also presented. Keywords: Fluorocarbons, Mass spectra, Perfluoro 3,3 diethylpentane and Pentanes.
