Title: "L-ENANTIOMERS SELECTIVE MEMBRANE FOR OPTICAL RESOLUTION OF ALPHA-AMINO ACIDS AND PROCESS FOR THE PREPARATION THEREOF"
Abstract:
The present invention provides a L-enantiomers selective composite membrane useful for separation of optical isomers and the process for the preparation thereof. The invention further provides a membrane based pressure driven separation process for separation of enantiomers from their mixture to obtain optical pure isomers. The present invention also provides a membrane based method for optical resolution of racemic mixtures of amino acids to obtain optically pure amino acids.
