| titleOfInvention | A kind of preparation method of perfluoro alkane |
| abstract | The invention discloses a kind of preparation methods of perfluoro alkane.Fluorination reagent is added in a kettle first, fluorination reagent is stirred at room temperature, and is passed through fluorine nitrogen mixed gas into reaction kettle and fluorination reagent is activated, then proceedes to stirring half an hour；Wherein, concentration of fluorine is 0.5~10% in fluorine nitrogen mixed gas, and fluorine nitrogen mixed gas mole is the 1~5% of fluorination reagent mole；After the completion of to be mixed, the overbottom pressure in reaction kettle is laid down, and perfluoroalkyl halide is added into reaction kettle and is reacted with solvent, reaction temperature is 150~200 DEG C, and the reaction time is 5~10h；Wherein, the molar ratio of perfluoroalkyl halide and fluorination reagent is (1 ︰ 1)~(1 ︰ 2), and the molar ratio of perfluoroalkyl halide and solvent is (1 ︰ 5)~(1 ︰ 15)；To after reaction, obtain reaction product, reaction product is cooled to room temperature, last distillation reaction product obtains perfluoro alkane.The present invention has many advantages, such as that equipment is simple, and operational safety is high. |
