木粉在离子液体中的溶解和降解
DOI: 10.3969/j.issn.1000-2006.2014.05.008, PP. 36-40
Keywords: 木粉,离子液体,1-烯丙基-3-甲基咪唑氯盐,溶解,降解
Abstract:
为探索木粉在1-烯丙基-3-甲基咪唑氯盐([amim][cl])中的溶解和降解问题,研究了预处理方式、溶解温度和时间以及液固比等对扶桑枝条木粉在[amim][cl]中的溶解率和析出率的影响;分析了影响木粉溶解的关键因素;探讨了阻碍木粉完全溶解的机制。结果表明:预处理方式和溶解温度是影响溶解的最重要因素,用5%naoh预处理木粉,溶解温度为80℃时,木粉在[amim][cl]中的溶解率达60.20%,析出率为46.57%,球磨、高浓度碱以及高温会加剧原料降解;木粉溶解率很高时,析出率较低,更多的是木粉中天然高聚物的降解,而非真正的溶解;较为温和的条件下,木粉难以全部溶解;木粉在[amim][cl]中的溶解度以及溶液黏度并非阻碍木粉完全溶解的因素,可能是因未溶纤维表面形成了胶体阻止了溶解的继续进行。
