| titleOfInvention | Process for purifying fluoroalkanes |
| abstract | The invention provides a method for purifying fluorine-containing alkane, which comprises the following steps: A) reacting the fluorine-containing alkane crude product with bromine and a reducing agent to obtain a first intermediate product; the reducing agent is selected from one or more of sodium sulfite or sodium thiosulfate; B) mixing the first intermediate product with an alkaline substance to obtain a second intermediate product; C) and adsorbing the second intermediate product to obtain the fluorine-containing alkane. According to the purification method of the fluorine-containing alkane provided by the invention, the fluorine-containing alkane crude product is subjected to addition reaction with bromine to remove double-bond compounds, then bromine and acidic impurities are further removed through a reducing agent and an alkaline substance, and then polar impurities and the like are removed through adsorption treatment, so that the fluorine-containing alkane with high purity is finally obtained. Experimental results show that the purity of the fluorine-containing alkane obtained by the purification method of the fluorine-containing alkane provided by the invention is above 97.97%. |
