Hello Bias Antonio, Ken is right, the NaOH dissolves a lot quicker in ethanol if heated. In order to make ethyl esters the quality of the reactants has to be high: ethanol min 99,5% pure and oil with a water content < 500 ppm and a stochiometric surplus of ethanol of at least 75% and why not 100% ? The economy of this is depending upon your possibilities of recover the excess ethanol.
