Abstract
Heterogeneous catalysts are considered as valuable materials in enhancing many chemical reactions to obtain specific products. Solid acid catalyst such as sulfated zirconia (SZ) is a promising catalyst with morphology and acidity properties that can be tuned up. In this research, we utilize the mesoporous sulfated zirconia modified by impregnation of gallium oxide by 2, 5, and 10% (wt) Ga2O3 (xGa-SZ; x = 2, 5, and 10) that were prepared by template-assisted sol-gel method as catalyst for the esterification of lauric acid. By using gas chromatography-mass spectrometry (GC-MS), we found that 5Ga-SZ and 10Ga-SZ were able to catalyze the esterification of lauric acid into methyl laurate, while 2Ga-SZ were inactive due to insufficient surface area and/or acidity. Thus, the solid acid xGa-SZ has potential to be used as heterogeneous catalyst for production of biodiesel.
