実験手順

It has been found that fractional distillation of a crude reaction mixture obtained in the manufacture of desflurane, for example, by reacting hydrogen fluoride with isoflurane over a bed of chromia catalyst, results in the removal of desflurane in the form of a desflurane/hydrogen fluoride azeotrope that boils below the boiling point of hydrogen fluoride.
