摘要: Abstract In this work, the Aleurites moluccanus oil was obtained in high yield from almonds (42%). The methyl and ethyl esters by transesterification of oil, have a content fatty acid unsaturated (>89%). Thermal properties inert oxidative atmospheres oils A. seed were estimated using Thermogravimetry − Derivative (TG/DTG). Low temperature investigated Differential Scanning Calorimetry (DSC). From experiments found that seeds thermally stable up to 210.9 °C; methanol biodiesel is 117.9 °C ethanol 122.0 °C air. nitrogen atmosphere 291.2 °C; 119.0 °C 123.3 °C. satisfactory performance at low temperatures with respect point crystallization, which below −11 °C. results showed Brazil can contribute as non-edible raw material for production biodiesel.
