Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2062-98-8, name is Perfluoro(2-methyl-3-oxahexanoyl) fluoride, A new synthetic method of this compound is introduced below., COA of Formula: C6F12O2
F[CF(CF3)CF2O]4CF(CF3)C(O)F, a precursor of hydrofluoroether F[CF(CF3)CF2O]5CH3, was formed by pentapolymerization of hexafluoropropylene oxide. To the reaction vessel, potassium fluoride (10.0 g), hexafluoropropylene oxide dimer (150.0 g) and diethylene glycol dimethyl ether (2.5 L) were added at 15 C under stirring.To the round bottom flask was introduced hexafluoropropylene oxide (830 g, 5.0 mol) over 1 hour.The lower layer of the acyl fluoride phase product is mainly composed of a hexafluoropropylene oxide tetramer, a hexafluoropropylene oxide pentamer and a hexafluoropropylene oxide hexamer, and the yield of the hexafluoropropylene oxide pentamer is 65%. The crude product was further purified by distillation to obtain a product of a hexafluoropropylene oxide pentamer having a purity of 99% as determined by gas chromatography, and used.In the next alkylation reaction. The structure of the product was characterized by infrared spectroscopy and 19F NMR.
The synthetic route of 2062-98-8 has been constantly updated, and we look forward to future research findings.
