| titleOfInvention | Method for synthesizing difluoroethanol by taking 2, 2-difluoro-1-chloroethane as raw material |
| abstract | The invention relates to a method for synthesizing difluoroethanol by taking 2, 2-difluoro-1-chloroethane as a raw material, which aims to solve the problems of harsh reaction conditions, low product yield and low purity in the prior art. The method takes 2, 2-difluoro-1-chloroethane and metal acetate as raw materials, and the raw materials react in a solvent to generate difluoroethyl acetate, and then the difluoroethyl acetate and alcohol undergo ester exchange reaction under the action of a sulfuric acid loaded silicon dioxide catalyst to generate difluoroethanol. The method has the advantages of mild reaction conditions, high product yield, high purity, reusable catalyst and suitability for industrial production. |
