| titleOfInvention |
A kind of separation method of high-purity electronic grade hexafluoropropane isomers |
| abstract |
The invention provides a method for separating high-purity electronic grade hexafluoropropane isomers, comprising the following steps: S1: washing with water to remove acid; S2: adsorption and dehydration; S3: catalytic conversion to convert the isomers into specified isomers Structure; S4: rectifying to remove other impurities; wherein, in step S3, a catalytic conversion tower is used in the form of a fixed bed reactor, wherein the surface active component of the catalyst loaded is platinum, and the loading amount is 0.2-0.8wt%. The separation method of the invention has the characteristics of high production efficiency, high depth of directional purification and stable process performance. |
