| 摘 要： | 以高碘酸钠溶液为氧化剂,在非均相条件下氧化纤维素,研究了溶剂等因素的影响.结果表明,含羟基溶剂对氧化反应有显著影响,能明显缩短反应时间,提高氧化纤维素中醛基的含量.当溶剂为5%(V/V)C2H5OH时,在适宜条件下,产物中醛基的质量百分含量可达0.561 2%,纤维素回收率为90.50%.

| Abstract: | The oxidation of cellulose with NaIO4 in non-homogeneous conditions was studied,some factors influencing the reaction were investigated.The results showed that when the solvent is 5%(V/V)C2H5OH,the aldehyde group content of oxycellulose is up to 0.561 2 % and the recycle ratio of oxycellulose is up to 90.50% at optimum conditions. |
