| titleOfInvention | Synthesis of polysaccharide ester |
| abstract | PURPOSE: To efficiently and inexpensively produce a cellulose ester, by directly esterifying cellulose or any other polysaccharide with an organic acid or a salt thereof in the presence of sulfonyl chloride. n CONSTITUTION: Cellulose (e.g., rayon, wood pulp or linter) or any other polysaccharide (e.g., chitin, chitosan or starch) is esterized with an organic acid (e.g., acetic acid or propionic acid) or a salt thereof (e.g., sodium acetate or potassium acetate) in the presence of sulfonyl chloride in an organic solvent (e.g., tosyl chloride, pyridine, DMF or dimethyl acetamide) usually 50°C for 2W20hr to provide a polysaccharide ester. n COPYRIGHT: (C)1989,JPO&Japio |
