Abstract:
1. A method of producing a filler for optical isomer separation, comprising the steps of: providing a polysaccharide having hydroxy or amino groups; dissolving the polysaccharide in a solvent; modifying some of the hydroxy or amino groups of the dissolved polysaccharide with molecules of a compound represented by formula (I) to produce a polysaccharide derivative wherein A is a chlorocarbonyl group, a carboxyl group, an isocyanate group, a glycidyl group or a thiocyanate group, X is an alkylene group which may be branched and has 1 to 18 carbon atoms or an arylene group which may be substituted, Y is an alkoxy group having 1 to 12 carbon atoms or a halogen group, R is an alkyl group which may be branched and has 1 to 18 carbon atoms or an aryl group which may be substituted and n is an integer of 1 to 3; and causing a carrier to carry the polysaccharide derivative through chemical bonding under an acidic condition.
