METHOD OF REMOVING HEXAFLUOROPROPYLENE DIMERS |
摘要 |
A method of removing hexafluoropropylene dimers ("HFP dimers"), dimer hydrides and other oligomers from a fluid is described. The method comprises heating the fluid to isomerize the HFP dimers to the thermodynamic isomer, and contacting the fluid with a tertiary amine (or salts thereof) to form a hexafluoropropylene dimer - tertiary amine adduct. The method may further comprise the step of separating the dimer adducts from the reaction mixture. |
