Verfahren zur Trennung eines fluorokohlenstoffenenthaltenden Produktstroms durch Distillierung

摘要

A product stream containing, inter alia, HCl, HF and fluorocarbons which form close boiling point azeotropes with HF is subjected to distillation using sidestream rectification in order to effect energy efficient separation of selected fluorocarbon/HF azeotropes from one another.
