Popis:	The amidation of fatty acid is an important reaction for synthesis of fatty alkolamines with a variety of pharmacological activities. The objective of this paper was to demonstrate the aminolysis direct and solvent of the triglycerides from the patawa oil by heterogeneous catalysis. The results of the amidation direct free solvents were favorable using 5% Al2O3 as catalyst, with a conversion of 94% at 24 h of reaction. After spectroscopic characterization, we decided explore the antimicrobial tests of the fatty amides (FAA) against the Staphylococcus aureus strain (ATCC 33591), showing a MIC activity of 1.9612 mg/mL and the fatty ethyl esters (FAEE) a 3.4125 mg/mL MIC. Therefore, the synthesis direct free solvents of FAA by Al2O3 from patawa oil was viable and innovative.
