Study on Preparation of 1H,1H,2H-Heptadecafluorodecene

1H,1H,2H,2H-1Iodide-Perfluorodecane was synthesized use perfluorooctyl iodide and ethylene as materials, then reacted with sodium methoxide /methanol to gain 1H,1H,2H-Heptadecafluorodecene. Influence factors such as kinds of solvents, raw material configuration, concentration and time in the process of dehydrogen iodide were studied mainly. Optimization was using 1,1,2-Trichloro-1,2,2-trifluoroethane as solvent, sodium methoxide /methanol (2mol/L), 1H,1H,2H,2H-1Iodide-Perfluorodecane(M1): sodium methoxide(M2) =1:2, reacted 12 hours, the yield of 1H,1H,2H-Heptadecafluorodecene was up to 80%.
