Abstract
Malonic acid ester was synthesized via the one‐step ozonolysis of palm olein. Malonic acid ester was spectroscopically characterized using gas chromatography mass spectroscopy (GC‐MS). Tungsten oxide nanoparticles were used as the catalyst, which was characterized via X‐ray powder diffraction (XRD) and field emission scanning electron microscopy (FE‐SEM). Tungsten oxide provided several advantages as a catalyst for the esterification malonic acid such as simple operation for a precise ozonation method, an excellent yield of approximately 10%, short reaction times of 2 h, and reusability due to its recyclability.
