Since the biodiesel program has been started in Brazil, the investigation of alternative sources of triacylglycerides from species adapted at semi-arid lands became a very important task for Brazilian researchers. Thus we initiated studies with the fruits of the Terminalia catappa L (TC), popularly known in Brazil as "castanhola", evaluating selected properties and chemical composition of the oil, as well any potential application in biodiesel production. The oil was obtained from the kernels of the fruit, with yields around 49% (% mass). Also, its fatty acid composition was quite similar to that of conventional oils. The crude oil of the TC was transesterified, using a conventional catalyst and methanol to form biodiesel. The studied physicochemical properties of the TC biodiesel are in acceptable range for use as biodiesel in diesel engines.
自从巴西启动生物柴油项目以来，对适应半干旱地区物种的三酰甘油替代来源进行调查，已成为巴西研究人员一项非常重要的任务。因此，我们开始对Terminalia catappa L（TC）的果实展开研究，这种果实在巴西俗称“castanhola”，我们评估了其油的选定特性和化学成分，以及在生物柴油生产中的任何潜在应用。该油是从果实的果仁中提取的，产率约为49%（质量百分比）。此外，其脂肪酸组成与传统油类相当相似。使用传统催化剂和甲醇对TC原油进行酯交换反应以生成生物柴油。所研究的TC生物柴油的物理化学性质在用作柴油发动机生物柴油的可接受范围内。
