บทคัดย่อ

In this work, the fractionation of sugarcane bagasse into cellulosic material and lignin was studied with various operating temperatures in 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) ionic liquid. It was observed that the dissolution temperature at 100ฐC for 22 h using [Bmim]Cl as solvent with bagasse loading of 5 wt.% gave the maximum regenerated cellulose 71%. Moreover, this temperature was sufficient to decrystallize the native structure of cellulose I to the low crystallinity of cellulose II, which was beneficial for subsequent hydrolysis step. The fractionation process at temperature lower than 100ฐC was not enough to dissolve bagasse whereas the process at higher temperature than 120ฐC generated higher amount of lignin in regenerated cellulosic material that led to the remaining structure of cellulose I in sample. Moreover, the ionic liquid was observed to be reusable. The reusability tests showed that lignin was a major impurity in recovered ionic liquid that affected on impurity of regenerated cellulosic material.
