Isosorbide derived from biomass is important for the industrial raw material. And it is produced through dehydration of sorbitol by using acid catalyst. We have compared the processes in presence of acid catalyst by changing various parameters such as catalyst, catalyst concentration, solvent and reaction temperatures. In addition, we observed the reactivity of sorbitol under various catalysts. As the results of the experiments using heterogeneous catalysts, the selectivity of isosorbide is 84.2%,78.5% and 69.5 when we use sulfated copper oxide calcined at 650℃, Amberlyst15 and Bi2(SO3H)3-LB2. |
