ABSTRACT:
Hydroxyalkyl ethers of hydroxyalkoxy polysaccharides are prepared by reacting the corresponding polysaccharide first with an epoxide in an aqueous alkaline medium, and then with an epoxide in the presence of a Lewis acid catalyst in a nonaqueous, nonalcoholic organic solvent. The resulting products are hydrophobic and strongly lipophilic, and are outstanding substrates for liquid-gel chromatography.
