Cellulose conversion to glucose is one of the crucial processes in the transformation of biomass to biofuels and other platform chemicals. In this research, we introduced the synthesis and hydrolysis of a cellulose derivative in an assistance of ionic liquid to glucose. A new type of water soluble cellulose, ionic cellulose (IC), was synthesized by the reaction of ionic liquid and cellulose. Due to its good solubility in water, this cellulose derivative was expected to give a good performance in hydrolysis. The hydrolysis of IC was conducted in the presence of several kinds of acid catalyst. Among the tested catalysts, sulfonated active carbon showed the highest yield of glucose with 43% and 54% at 150 oC and 180 oC, respectively. This catalyst also maintained its catalytic activity after several time reuses. |
