Methods for separation of organic and pharmaceutical compounds by different polymer materials
Pravin Ganeshrao Ingole,Neha Pravin Ingole 한국화학공학회 2014 Korean Journal of Chemical Engineering Vol.31 No.12
The discrimination of enantiomers is a challenging task in separation technology, and using a membraneis most promising for separating enantiomers from racemic mixture. The optical resolution of chiral compounds is ofinterest to researchers working in a variety of fields from analytical, organic and medicinal chemistry, to pharmaceu-tics and materials, to process engineering for fabricating pharmaceuticals, agrochemicals, fragrances and foods, and soon. There is considerable demand for separation techniques appropriate for the large-scale resolution of chiral molecules. The separation of chiral compounds using chiral or achiral/non-chiral polymeric membranes with or without chiralselector represents a promising system for future commercial applications. This review focuses on an active field ofchiral separation, membrane-based enantioseparation technique, which has potential for large-scale production of single-enantiomers. Enantiomeric separation by membrane processes has been studied using various configurations of liquidand solid polymer membranes. Selectivity and permeability of liquid-membranes is reasonably good because the rateof diffusion of solute molecules is high in liquids but has inferior durability and stability. Solid polymer membraneshave inferior permeability because diffusion of solute through solids is slow but quite stable and durable; however,commercial application of membrane technology for optical resolution is yet to be realized. Several chiral separationmembranes were prepared from chiral polymers where enantioselectivity was generated from chiral carbons in the mainchain. However, it is rather tricky to generate excellent chiral separation membranes from chiral polymers alone, becauseracemic penetrants mainly encounter the flexible side chains of the membrane polymers.
