| titleOfInvention | Fluorination process of perfluoro compound containing 1, 3-dioxolane ester or 1, 3-dioxane ester |
| abstract | The invention provides a fluorination process of perfluorinated compounds containing 1, 3-dioxolane esters or 1, 3-dioxane esters, which comprises the following steps: placing a first fluorinated solvent and a catalyst in a reaction kettle; the catalyst is selected from one or more of boron trifluoride, cobalt trifluoride, bismuth trifluoride and arsenic trifluoride; dissolving a hydrocarbon substrate and a surfactant in a second fluorination solvent to obtain a raw material solution; the surfactant is selected from one or more of perfluorononanoic acid, perfluorooctanesulfonic acid and tetrabutylammonium fluoride; the hydrocarbon substrate is in a structure of a formula (I) or a formula (II); and carrying out fluorination reaction on the raw material liquid and fluorine gas in the reaction kettle to obtain the perfluorinated compound. In the invention, in a specific fluorine-containing solvent, low-cost hydrocarbon is used as a starting material, and a special fluorine-containing surfactant and a catalyst are used for directly contacting fluorine gas with the starting material so as to directly convert the fluorine gas into a perfluorinated compound. The method is simple, low in cost and high in yield. |
