The optimization process of biodiesel production using the ionic liquid (IL) piridinium p-toluenesulfonate [HPy][p-TSA] as catalyst in methanolic reaction with babassu oil is described. The ionic liquid efficiency in babassumethanolic biodiesel was verified by complete factorial design, response surface methodology (RSM) and the analysis of variance (ANOVA) was used to evaluate the statistical model. The ANOVA results show the 95 % confidence level, only the molar ratio MeOH:oil and temperature significantly affected the formation of methyl esters. The best reaction conditions in the process were in the molar ratio alcohol:oil 15:1, IL 2.0 % w/w, temperature 130 °C and 8 hours of reaction. The maximum conversion of the biodiesel with the piridinium p-toluenesulfonate was around 88.6 %.
