| titleOfInvention | Method for preparing high-purity octafluoropropane |
| abstract | The invention relates to a method for preparing high-purity octafluoropropane, which comprises the following steps: setting the reaction temperature to be 50-250 ℃ in a reactor, and reacting cobalt trifluoride serving as a catalyst and hexafluoropropylene and fluorine gas serving as reaction gases to prepare octafluoropropane; the molar ratio of the hexafluoropropylene to the fluorine gas is 1: 2-6. In the preparation method, cobalt trifluoride is used as a catalyst, so that continuous reaction can be realized, the addition reaction of hexafluoropropylene and fluorine gas is promoted, the conversion rate of hexafluoropropylene is almost 100%, the yield of octafluoropropane can reach over 90%, the reaction selectivity is good, and the content of byproducts is low. The obtained crude product can be used for preparing high-purity octafluoropropane after subsequent purification treatment, and the method is a low-cost and high-efficiency production method of octafluoropropane capable of realizing industrial production. |
