| 中文摘要: |
| 以毛竹为原料，采用甲醛辅助氯化胆碱/乳酸（ChCl/LA）低共熔溶剂对毛竹进行预处理，并通过漂白及酸水解工艺制备得到微晶纤维素（MCC）。结果表明，在ChCl与LA物质的量比1∶5、预处理温度120 ℃、预处理时间3 h的条件下进行甲醛辅助ChCl/LA预处理，固形物得率58.9%，固形物中纤维素含量59.6%，半纤维素去除率62.0%，木质素去除率69.9%；经进一步漂白得到的浆料中纤维素含量高达92.3%；酸水解后制得的MCC（得率84.8%）保留了纤维素I型结晶结构，结晶度指数高达73.2%，纤维素聚合度148，且具有良好的分散稳定性和热稳定性，Zeta电位绝对值接近25 mV。 |
| Abstract: |
| Using Moso bamboo as the raw material， the bamboo was pretreated with a formaldehyde-assisted choline chloride/lactic acid （ChCl/LA） deep eutectic solvent， and microcrystalline cellulose （MCC） was prepared through bleaching and acid hydrolysis processes. The results showed that under conditions of ChCl to LA molar ratio of 1∶5， pretreatment temperature of 120 ℃， and pretreatment time of 3 h， the formaldehyde-assisted ChCl/LA pretreatment prepared a solid product with a yield of 58.9%， cellulose content of 59.6%， hemicellulose removal rate of 62.0%， and lignin removal rate of 69.9%. the pulp obtained after further bleaching had a cellulose content as high as 92.3%. The MCC prepared after acid hydrolysis retained the Type I crystalline structure of cellulose， with a yield of 84.8%， cellulose polymerization degree of 148， and crystallinity index as high as 73.2%， and exhibited good dispersion stability and thermal stability， its absolute value of Zeta potential was close to 25 mV. |
