Popis: Levulinic acid (LA) comes from the family of ketone and carboxyl, which contributes to a very versatile building block for the synthesis of high value-added chemicals. Glucose can be converted into LA at certain conditions preferably at temperature of 80 °C–200 °C. Hence, a study on the effect of reaction and calcination temperature towards the conversion of glucose to LA was conducted. The effect was studied by varying the reaction and calcination temperature from 80 °C to 100 °C and 200 °C to 400 °C respectively. The solid acid catalyst was prepared using a wet impregnation method to incorporate 30 wt% SO42- on silica alumina. FTIR analysis was conducted to characterize the solid acid catalyst where the catalytic conversion took place in a batch reactor. It was found that the highest temperature used for the reaction (100 °C) contributes to a higher conversion of glucose to LA which is 56.8%. The reaction took place for 6 h. Meanwhile, as for the effect of calcinations temperature, it was revealed that lower temperature of calcinations favors the reaction where it tends to retain the SO42- content on the silica alumina support as shown in the FTIR analysis. This is because up to 48% of glucose was converted into LA. From this study, it is proven that parameters such as reaction and calcinations temperature highly influence the conversion of glucose to LA.
