The extraction of ara double dagger a oil was carried out from seeds, and the fatty acid profile of this oil indicates the predominant presence of linoleic acid (81.38%). Thermogravimetry, derivative thermogravimetry, and differential scanning calorimetry (DSC) were used to characterize this oil. In addition, this oil was evaluated by DSC from 25 to -60 A degrees C, where the crystallization behavior was verified. Details concerning thermal decomposition as well as data of kinetic parameters of these stages have been described here. The kinetic behavior of the thermal decomposition was evaluated from several heating rates with mass samples of 5 and 20 mg in open crucibles under nitrogen and synthetic air atmospheres.1281-1286engAraca oilThermal behaviorKinetic parametersCrystallizationArtigo10.1007/s10973-011-1700-9WOS:000304621000059Acesso restrito849831089181008274713101139991400000-0002-7984-5908
