The synthesis of glycerol carbonate (GC) from glycerol and di-Me carbonate (DMC) catalyzed by oil palm empty fruit bunch ash (EFBA) was developed in this work. The catalyst was calcined at a temperature range of 300-600°C, and the effect of temperature was correlated with the catalyst structure-activity relationship, the total basicity, and basic strength. The catalyst characteristics were investigated by the N2-adsorption-desorption, Fourier transform IR, X-ray diffraction, XRD and Scanning electron microscope and energy dispersive spectroscopy, SEM/EDS. The results show that increasing calcination temperature propagates crystalline phase transition from KAlSiO4 to K2Mg(SiO4) by incorporating more K+ in the tetrahedral framework of SiO2 connected with Mg2+O4. Consequently, catalyst basic strength was enhanced and a significant amount of basic sites was generated with a corresponding increase in the GC yield. Also, the reaction temperature, initial DMC/glycerol molar ratio, catalyst dosage, and reaction time influence the yield of GC. Hence, 95.7% GC yield was achieved under 5 weight% catalyst concentration, 90°C, and initial DMC/glycerol molar ratio of 3:1 under 45 min reaction time. The catalyst sustained 85.2% GC yield after four times reuse, indicating relatively high stability without severe deactivation.
