Abstract
A process is disclosed for separating HF from organics by passing a mixture of HF and organics through a column or bed containing a polymer which sorbs the HF leaving an essentially pure organic stream. The HF may be recovered from the polymer, or the organics may be recovered with reduced HF concentration. The HF and organics may form an azeotropic or azeotrope-like mixture.
