摘要:The instant invention relates to azeotropic or azeotrope-like compositions of hydrofluoric acid with at least one of 1,1-dichloroethane, 1-chloro-1-fluoroethane and 1,1-difluoroethane. The invention also relates to manufacturing processes for separating hydrofluoric acid from a mixture comprising hydrofluoric acid and one or more of the 1,1-dihaloethane.
