The mass yield of a base-catalyzed soybean oil methanolysis was maximized to 87.09 (wt/wt % ) through response surface methodology with five levels and four factors. An economy of 33 % methanol, 33 % sodium hydroxide, and 50 % reaction time was achieved in relation to other optimization researches which were previously reported in the literature. The obtained biodiesel attends the ANP quality standards for the following items: ester amount wt % , free glycerol (wt/wt % ), mono-, di-, and triacylglycerols (wt/wt % ), and total glycerol (wt/wt % ).
