The separation of cis and trans isomers is relevant for biological and nutritional applications, silver-exchanged zeolite Y was prepared and applied for the treatment of mixtures of cis and trans geometrical isomers of mono- and polyunsaturated fatty acid methyl esters (FAMEs) cis FAMEs were adsorbed into zeolite with a high degree of selectivity (cis/trans ratio in the range of 19-32) The effectiveness was clue to the synergism of the pi-complexation between the silver ion and the double bonds and the different FAME structures trapped into the zeolite cages Some indication of the complex stabilities came from theoretical studies using unsaturated lipids A prototype cartridge was also designed For application in the fractionation of cis/trans FAME mixtures (C) 2010 Elsevier Ltd All rights reserved
