ABSTRACT:
An alkyl-phenylcarbamate derivative of a polysaccharide has in 80 to 100 percent of hydrogen atoms of the amino and hydroxyl groups an alkylphenyl-carbamoyl group having the formula (I): ##STR1## in which (1) at least one of R1 to R5 is a straight alkyl having 4 to 8 or a branched alkyl having 3 to 8 carbon atoms or at least two of R1 to R5 each are a straight alkyl having 1 to 3 when the polysaccharide is cellulose; (2) at least one of R1 to R5 is a straight alkyl having 1 to 8 carbon atoms or a branched alkyl having 3 to 8 carbon atoms when the polysaccharide is any one other than cellulose; and the other(s) of R1 to R5 is hydrogen. It is useful to optical separation of a racemic mixture.
