Alkyl-phenylcarbamate derivative of polysaccharide |
| abstract |
An alkylphenylcarbamate 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):n n wherein (1) at least one of R₁ to R₅ is a straight alkyl having 4 to 8 carbon atoms or a branched alkyl having 3 to 8 carbon atoms or at least two of R₁ to R₅ are a straight alkyl having more than 1 or 3 carbon atoms when the polysaccharide is cellulose; (2) at least one of R₁ to R₅ is a branched alkyl having 3 to 8 carbon atoms when the polysaccharide is not cellulose; and the other R₁ to R₅ are hydrogen, with the proviso that alkylphenylcarbamate derivatives wherein both of R₁ and R₅ are an alkyl having 3 to 8 carbon atoms are excluded and the further proviso that cellulose-tris(4-t-butylphenylcarbamate) and amylose-tris(4-t-butylphenylcarbamate) are excluded. n It is useful to optical separation of a racemic mixture. |
