%X The optimization of the yield of transesterification reaction to obtain the B100 biodiesel has been studied using sodium hydroxide, potassium hydroxide, methoxide and sodium ethoxide as catalysts. We applied a randomized simplex centroid mixture and the results of optimization indicate, when using methanol, a yield of 97.61% when using 30,77% NaOH and 69,23% of sodium methoxide and a yield of 89,32% when using only the sodium ethoxide whit ethanol. Chromatographic analysis indicated that the B100 biodiesel obtained is within the parameters established by Brazilian Legislation.
