Synthesis of solid enantioselective macromer of trimesic acid for the enantiomeric separation of chiral alcohols
Pravin G. Ingole, Hari C. Bajaj and Kripal Singh

 
Abstract
    Enantioselective macromer of trimesic acid was prepared using S(−) menthol with trimesoyl chloride on polyimide (PI) ultrafiltration membrane. The chemical composition of macromer as well as polyimide ultrafiltration membrane was determined by ATR-FTIR Spectroscopy. The optical resolution of chiral alcohols was performed in pressure driven process. The effect of monomer solutions concentration, effect of air-drying time of S(−) menthol solution, effect of reaction time, effect of operating pressure, effect of feed concentration of racemate on the performance of macromer was studied. The synthesised material exhibits separation of chiral alcohols (menthol ~23% and sobrelol ~21%).
