Abstract
Crude sevoflurane product comprising unacceptably high levels of HFIP can be purified by combining the crude sevoflurane product with sufficient water to produce a multiphase mixture, fractionally distilling the multiphase mixture, removing sevoflurane from the distilling multiphase mixture as an azeotrope with water, and separating substantially pure sevoflurane from the azeotrope.
