SYNTHESIS AND CHARACTERIZATION OF BENZYL ALGINATE

Alginate is a hydrophilic natural polysaccharide from brown seaweed with a wide application. Owing to the increasing interest in introducing the hydrophobic group into the alginate molecule, alginic acid and benzyl chloride were Let to react in DMF with silver oxide as catalyst at room temperature to synthesize benzyl alginate, which was characterized by IR, 'H-NMR, GPC, UV, TG, and DTA. Solubility measurement shows synthesized benzyl alginate was soluble in formamide, glycol, propylene glycol, and water, and swellen in DMF.
