Abstract

This study was aimed to investigate the chemical and biological characteristics of Poon trees Calophyllum inophyllum L. and its extracted oil as starting material for synthesizing biodiesel. Density, seed yield and biomass of Poon trees were investigated in the field for biological characteristics while fatty acid composition and oil quality were determined as chemical characteristics. Seed yield of a ten-year Poon tree was 74.8 kg/tree/year. Poon tree density and biomass were 625 trees/ha and 0.16 ton/tree, respectively; oil yield was 13.4 L/tree/season or 17,187 L/ha/year. Fatty acid composition of poon oil was found to include 2.35%, 7.62%, 12.4% and 3.44% of stearic, oleic, linoleic and palmitic acids, respectively. Acid value; saponification value; iodine value and oil density were 10.5, 184, 88.8 and 0.94 Kg/L, respectively. Biodiesel produced from the extracted Poon oil contained 91% of fatty acid methyl esters.
