| 中文摘要 | Cellulose acetates with low degree of substituent(DS) were homogeneously synthesized in an Ionic liquid, 1-allyl-3-methyl-imidazolium chloride (AmimCl). Under mild reaction conditions, cellulose monoacetates(CMA) with the DS in a range from 0.34 to 1.60 were obtained. NMR analysis shows that the distribution of acetyl moieties among the three OH groups of anhydroglucose unit is C6>>C3 > C2 for the synthesized CMA. The water solubility measurement shows that the CMA samples with the DS ranging from 0.65 to 1.06 are readily dissolved in water. The relationship between the structure and water solubility of CMA was briefly discussed. |
