| titleOfInvention | Method for synthesizing 1, 2-difluoroethane and 1,1, 2-trifluoroethane |
| abstract | The invention relates to a method for synthesizing 1,2 difluoroethane and 1,1,2 trifluoroethane, which belongs to the field of synthesisIn the field of organic chemical synthesis. The method for synthesizing the 1, 2-difluoroethane and the 1,1, 2-trifluoroethane is characterized by comprising the following steps: ethylene (formula CH) 2 ＝CH 2 ) And chlorine (formula Cl) 2 ) Heating under the action of catalyst to produce mixture of 1, 2-dichloroethane and 1,1, 2-trichloroethane, and heating the mixture with hydrogen fluoride (formula HF) under the action of fluorination catalyst to produce 1, 2-difluoroethane and 1,1, 2-trifluoroethane. The raw materials are cheap and convenient to obtain; the product is simple to separate and purify; the industrial production is easy to realize; less industrial three wastes. |
