English abstract A simplex-centroid design was applied to optimize conditions for obtaining B100 biodiesel from sunflower oil using different catalysts with methanol and ethanol as process variable. Sodium methoxide was indicated as the best catalyst in the transesterification reaction with methanol at a 98.30% yield. Reaction yield was optimized only to 89.65% when ethanol as process variable and KOH as catalyst were employed. Tests with the obtained products, in optimal conditions, indicated that they were within the parameters established by Brazilian legislation and by the European Union
Portuguese abstract O delineamento simplex-centroide foi aplicado para otimizar as condições de obtenção de biodiesel B100 de óleo de girassol, utilizando diferentes catalisadores, com metanol e etanol como variável de processo. A reação de transesterificação, usando metanol, indicou o metóxido de sódio como o melhor catalisador com rendimento de 98,30%. Usando etanol como variável de processo e KOH como catalisador, o rendimento da reação foi de somente 89,50%. Os ensaios com os produtos obtidos, nas condições ótimas, indicaram que eles estavam de acordo com os parâmetros estabelecidos pela legislação brasileira e pela União Europeia
