| titleOfInvention | A kind of preparation purification method of trifluoromethyl sulfur pentafluoride |
| abstract | The present invention relates to the technical field of the fluorine chemical industry, in particular to a method for preparing and purifying trifluoromethyl sulfur pentafluoride. The method comprises the following steps: (1) feeding Fluorine gas or fluorine-nitrogen mixed gas reaction to prepare cobalt trifluoride; (2) carbon disulfide steam is introduced into the reactor heated to 50-500°C for reaction, and the generated gas enters the condenser for purification after passing through the settling tank, and first passes through the first The light components are discharged from the condenser through the second exhaust, and trifluoromethyl sulfur pentafluoride is discharged through the second liquid discharge. This method uses carbon disulfide and cobalt difluoride as raw materials to prepare trifluoromethyl sulfur pentafluoride, and then obtains a product with a purity greater than 90% through batch distillation. This method is practical, relatively safe and environmentally friendly, and has low overall cost. Good economic benefits and application prospects. |
