Abstract:

The Biofuel Act of 2006 mandates the blending of biodiesel in all diesel fuel sold across the country. Having an increase demand on using the biofuels, the country needs more alternative sources. The seed of Terminalia catappa, one of the most abundant trees in the Philippines contains 51.2 percent oil (called catappa oil).

Talisay or catappa oil was extracted using the solvent method, a mixture of hexane and isopropanol wih 3:2 ratios. The dried seeds were ground to fine consistence 60mL of hexane along with 40mL isopropanol was mixed in a beaker and allowed to soak for 5-10 minutes. Catappa oil was collected through decantation.
