  • L-ENANTIOMERS SELECTIVE MEMBRANE FOR OPTICAL RESOLUTION OF ALPHA-AMINO ACIDS AND PROCESS FOR THE PREPARATION THEREOF
    Publication number: 20150005530
    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.

  • Polyamide nanofiltration membrane useful for the removal of phospholipids
    Publication number: 20100224563
    Abstract: The present invention provides a polyamide nanofiltration membrane and the process for the preparation thereof thereof. The invention further provides a process for the removal of phospholipids from rice bran oil (edible grade) by using novel polyamide membrane. The oil permeated through the membrane is 90 to 95% free from phospholipids in comparison to feed oil with about 90% reduction of color in comparison to feed oil.
