| 中文摘要: |
| 甲壳胺（DAC-85）在水-甲醇中于弱酸性条件下与月桂醛发生还原N-烷基化反应，制得N-十二烷基甲壳胺。进一步在55%氢氧化钠溶液-异丙醇中与氯乙酸反应制得O-羧甲基化甲壳胺衍生物，最终获得了两亲性甲壳胺衍生物，并作了元素分析及红外测定。 |
| English Summary: |
| N alkylated Partially deacetylated chitin(DAC 85)was prepared via reductive N alkylation in aceques MeOH with lauraldehyde.Further,O carboxymethlation of N alkylatedchitosan was performed in 55% NaOH with carboxymethy chloride.A new type amphiphilic chitosan derivative was achieved.Elementary analysis and IR spectrume was performed to study the characterization of the chitosan derivative. |
