PURPOSE: To provide a separating agent containing a substituted aromatic derivative of a polysaccharide as an active component, having improved separating effect, especially the optical resolution effect by selecting the substituent groups, thereby varying the separating and adsorbing characteristics, and useful for the separation of various compounds, especially optical isomers. n CONSTITUTION: Various compounds, especially optical isomers are separated from each other economically by the chromatographic process such as gas-, liquid- or thin film chromatography or membrane separation technique, using a separation agent containing, as an active component, a substituted aromatic ester of a polysaccharide wherein the alcohol fragment is preferably the polysaccharide such as cellulose, amylose, β-1,4-chitosan, etc. and the carboxylic acid fragment is acyl of formula I Wformula III (XWZ are alkyl, alkenyl, alkynyl, NO 2 , halogen, NH 2 , alkyl-substituted amino, CN, OH, alkoxy, acyl, etc.; l is integer of 1W5; m is integer of 1W7; n is integer of 0W5, preferably 0). n COPYRIGHT: (C)1985,JPO&Japio |
