| titleOfInvention | Preparation method for 1-chlorine-1,1-difluoroethane |
| abstract | The invention provides a preparation method for 1-chlorine-1,1-difluoroethane. The target product 1-chlorine-1,1-difluoroethane with high purity is prepared from ethyne serving as an initial raw material by the steps of addition and chlorination. The price of the raw material ethyne used in the method is lower than that of raw materials such as vinylidene chloride and trichloroethane in the conventional method, so production cost is reduced. By the method, byproducts are few and the target product has high purity. The prepared 1-chlorine-1,1-difluoroethane can serve as a refrigerating agent, a foaming agent, a propelling agent, a cleaning agent, an aerosol jetting agent and the like. |
