CELLOOLIGOSACCHARIDE DERIVATIVE AND PROCESS FOR PRODUCING THE SAME

A novel nonionic surfactant consisting of a cellooligosaccharide derivative wherein the position of introduction of hydrophobic groups is unevenly distributed along the main chain of cellulose; and a process for producing the same. There is provided a cellooligosaccharide derivative comprising a hydrophobic moiety of alkylated glucose or cellooligosaccharide and, bonded thereto in a block fashion, a hydrophilic moiety of monosaccharide or oligosaccharide.

Synthetic conversion of cellobiose into the glycal-type monomers and their polymerization

A pair of disaccharidic glycals thoroughly O-benzylated except the 4'- or the 6'-hydroxyl groups were prepared as the monomers for iodonium ion- promoted polymerization, which proceeded under dark conditions to give polysaccharides of more than DP 12 (24 saccharide). Reductive removal of the iodine atom and subsequent deprotection gave polysaccharides alternatively composed of β-D-glucopyranosyl and 2-deoxy-α,β-D-glucopyranosyl residues.
