  • Liquid membrane separation of enantiomers
    Patent number: 6485650
    Abstract: The invention is related to a method for separating enantiomers in a supported liquid membrane module by contacting the liquid membrane which may contain a carrier and a phase transfer agent with a feed fluid containing a racemic mixture whereby an enantiomer is transported into the liquid membrane and thereafter contacting the liquid membrane with a sweep fluid whereby an enantiomer is transported from the liquid membrane into the sweep fluid. The enantiomer is then recovered from the sweep fluid. The liquid membrane module is constructed in such a way that the feed fluid and the sweep fluid are adjacent to, but on opposite sides of, the liquid membrane and the feed and sweep fluids have a substantially continuous interfacial contact along the length of the liquid membrane.
