Abstract
A Chiral polymer from 1,2-bis(2-methyl-1-triethylsiloxy-1-propenyloxy)ethane and dialdehyde from adipoyl chloride and 4-hydroxy benzaldehyde has been prepared in gram scale level and characterized by IR, NMR, TGA, DSC, optical rotation and Circular dichrosm (CD) study. The same was used for preparation of enantioselective membrane by phase inversion technique and the membrane was characterized for pore size and surface morphology through SEM (Scanning Electron Microscope) analysis. The enantioselective property of the membrane in the resolution of racemic compounds was studied using aqueous solution of Atenolol, Captopril, Propranolol hydrochloride and Salbutamol as feed solution. Pressure driven membrane processes were studied under pressure 4.84 × 10−2N/m2, 24.22 × 10−2N/m2 and 48.44 × 10−2N/m2. The Effect of feed concentration and operating pressure on membrane performance were studied differently. Solution diffusion model have been used to explain the permeation behaviour of the membrane. From this type of membrane 95% ee and 6.4mg/m2 h of flux were obtained.
