Abstract
The invention relates to a process for the high yield, cost efficient means of separating enantiomers. The process utilizes a supported liquid membrane and a chiral carrier which selectively complexes with one of the two enantiomeric optical configurations. The invention is also directed to an apparatus adaptable to the continuous and staged separation of enantiomers. In one embodiment, the apparatus utilizes a semi-permeable barrier and source and receiving locations each of which may be kept at temperatures which facilitate the complexation and dissociation processes.
