Biofuel production from waste cooking oil (WCO) is an important alternative for using in generating biodiesel also it helps in the reuse of a pollutant. This work seeks to determine the best performance of the production process of ethyl esters from the parameters: molar ratio WCO/ethanol (1: 5-1: 7), percentage of catalyst by weight (0.5 to 0.7%wt), reaction temperature (50-60 °C) and washing agent (40 °C Water - acetic acid) using the transesterification process by homogeneous catalysis alkaline (NaOH). The process was carried out in two steps, the first stage of esterification and other one transesterification with a reaction temperature of 60 °C, molar ratio WCO: ethanol 1: 7 and water as washing agent. The biodiesel produced possesses physicochemical characteristics according to ASTM D6751 standard and 93.5% yield of ethylesters. The optimal conditions enable the use in biofuel “boiler” which functional diesel.
