In this paper, it is presented an experiment carried out with the objective of knowing the optimum roductionprocess in order to generate bio diesel by alkaline transesterification, from residual vegetable oils from theRestaurants in San Borja. In order to do so, first of all of the residual vegetal oil collected was analyzed, then itwas determined the concentration of methanol (%v/v), the concentration of potassium hydroxide (%p/p) andthe optimum reaction time, and lastly, it was determined the bio diesel quality produced. The results showed that it is possible to generate biodiesel from the collected oil, due to its grade of acidity(1,56%) was lower than 3%. The optimum conditions to get the maximum conversion of the reaction wereachieved when it was used a methanol concentration of 30%, a concentration of potassium hydroxide of 0,4%regarding the weight of the oil and a reaction time of 3:30 minutes at a constant temperature of 60%. Under these conditions it was obtained a performance of biodiesel of 85,97%. Biodiesel obtained under the best reaction conditions will be analyzed four fuel properties, finding that the kinematic viscosity was 5,5 cSt, the acid number was 0,68 mg KOH / g, the sulfated ash was 0,0478% and Conradson Carbon was 0,142%.
