In this study ZrSO4-SiO2 catalyst with EDTA template was used as a catalyst which was synthesized by calcination method. The preparation of sulphated zirconium impregnated silica catalyst was carried out at various temperatures, such as 400°, 500°, 600°, 700° and 800°C. This study aims to determine how the temperature of the catalyst ZrSO4-SiO2 EDTA template influences. The XRD results on …
