| titleOfInvention | Method for synthesizing 1, 1-difluoro-2, 2-dichloroethane by using R142b hazardous waste |
| abstract | The invention discloses a method for synthesizing 1, 1-difluoro-2, 2-dichloroethane by using R142b hazardous waste, comprising the following steps of I, synthetic reaction; step two, distillation; and step three, rectifying. The method has the main advantages that hazardous wastes are comprehensively utilized, 1, 2-trichloro-2, 2-difluoroethane (R122) is contained in the hazardous wastes generated in the production of the 1, 1-difluoro-1-chloroethane (R142b), and the R142b hazardous wastes are mainly treated by incineration at present and pollute the environment. Wherein R122 contained in the product can be dechlorinated to generate 1, 1-difluoro-2, 2-dichloroethylene, and then hydrogenated to generate 1, 1-difluoro-2, 2-dichloroethane (R132 a). |
