摘要： A separatory agent for optical isomers which contains a polysaccharide derivative as an active ingredient, wherein the polysaccharide derivative serving as an active ingredient is one formed by replacing at least part of the hydrogen atoms of the hydroxy groups and amino groups of a polysaccharide with at least one member selected between a benzoyl group having a specific alkyl group and a carbamoyl group in which one hydrogen atom has been replaced with an aromatic group having a specific alkyl group. It is a novel separatory agent for optical isomers which has the high ability to asymmetrically identify the target compound to be analyzed and isolated.

摘要： A process for producing a high-purity polysaccharide containing hydrophobic groups which comprises: a first-stage reaction in which a C12-50 hydroxylic hydrocarbon or a sterol is reacted with a diisocyanate compound represented by the formula OCN-R -NCO (wherein R is a C1-50 hydrocarbon group) to produce a hydrophobic compound the molecule of which has an isocyanate group and a residue of one molecule of the reacted hydrocarbon or sterol; a second-stage reaction in which the hydrophobic isocyanate compound obtained in the first-stage reaction is reacted with a polysaccharide to produce a polysaccharide having, as hydrophobic groups, either C12-50 hydrocarbon groups or steryl groups; and purifying the product of the second-stage reaction with a ketone solvent.

摘要： The invention provides modified starches having unique gelling properties which are prepared by chemically reacting an amylose containing starch base with an etherification or esterification reagent which will introduce a long linear hydrocarbon chain substituent therein. The aqueous gels formed by the starches are thermally and pH-reversible and the thermally-reversible gels are hot gels. The invention further provides an improved process for preparing starch halfacid esters in water by reacting starch under alkaline conditions with a hydrophobic-substituted cyclic dicarboxylic acid anhydride in the presence of a phase transfer agent.
