application | 1H,1H, 2H-perfluoro-1-decene, also known as perfluorooctylethylene, can be used as monomer and chemical intermediate, and can be used in laboratory research and development process and chemical production process. |
preparation | perfluorooctane iodide (520g,1.16mmol),Na2S2O4(20.9g,0.12mol),Na2HPO4(21.5g), acetonitrile (900mL) and water (300mL) are added to a 2L autoclave, and ethylene gas is introduced to make the pressure reach 40atm. After 3 hours of continuous reaction at 40-45 ℃, a significant decrease in ethylene pressure was found. 19FNMR tracking reaction found that the raw material has completely reacted, stopped the reaction, discharged excess ethylene gas, separated the lower organic layer, washed with water, washed with saturated salt, dried with anhydrous sodium sulfate, and removed the organic solvent under vacuum to obtain the compound perfluorooctane ethyl iodine is a white solid (525g, yield 95%, mp56-57 ℃). KOH(7.0g, 0.1mol) and methyl 30mL were added to a 250mL three-mouth flask equipped with a reflux condenser tube, a dropping funnel and a thermometer. The compound perfluorooctane ethyl iodine (47.4g, 0.1mol) was dissolved in 100mL Freon-113 solvent, and then the solution was slowly added dropwise into the methanol solution of KOH. The reaction is exothermic and a large amount of solid is generated. After dropping, heat and reflux for 3 hours. The reaction mixture was poured into 250mL of water, the organic layer was separated, dried with anhydrous Na2SO4 and distilled to obtain the compound perfluorooctylethylene (28.0g, yield 81%). |
