| titleOfInvention | A kind of method and device of two fluoracyl fluorides of nonmetal catalyzed preparation |
| abstract | The present invention provides a kind of method and devices of two fluoracyl fluorides of nonmetal catalyzed preparation.This method utilizes N doping catalyst, with 1,1,2,2- tetrafluoro ethyl etherate for raw material；Under 160~240 DEG C of gas phases of reaction temperature, reaction velocity be 50~200h ‑1 Under the conditions of reacted, generate two fluoracyl fluorides.Two fluoracyl fluorides of the generation can further be converted into ethyl difluoro with ethanol synthesis by importing in ethanol solution.The present invention avoids proposing environmentally protective non-metallic catalyst using catalyst such as traditional solid acids, good reaction selectivity, and raw material availability is high, and product purity is high, easy to industrialized production. |
