degree of deacetylation of chitosan 壳聚糖的脱乙酰度
This new technology needs lower NaOH concentration, shorter reaction time and less water washing than that of conventional NaOH aqueous solution method. The produced chitosan is of high degree of deacetylation (%D. D>90) and molecular weight (9.3 105).2.
该工艺的特点是低碱度,反应时间短,产品脱乙酰度高(%D.D>90),黏度大(分子量9.3×105),产率80%左右,与传统的水溶液碱液法比较可以节省70~80%的烧碱和2/3左右的洗涤水。
