dc.description.abstractBicuíba belongs to the Virola bicuhyba (Schott ex Spreng.) Warb species, Miristicaceas (Myristicaceae) family, which is frequently found in the Atlantic Forest of South and Southeast Brazil. Extraction of the Bicuíba oil was carried out and characterized by gas chromatography. The composition of in nature of this oil indicates that there is a predominance of saturated fatty acids with ~35 % lauric acid and ~40 % myristic acid. Details concerning the thermal behavior were evaluated by thermogravimetry, differential thermal analysis, and differential scanning calorimetry under oxygen and nitrogen atmospheres, showing thermal stability between 208 and 210 °C, respectively. Additionally, the kinetic studies were evaluated from several heating rates with a sample mass of 5 and 20 mg in open crucibles. The obtained data were evaluated with the isoconversional method kinetic, where the values of activation energy (Ea/kJ mol-1) were plotted in function of the conversion degree (α). © 2013 Akadémiai Kiadó, Budapest, Hungary.en
