Resumen:
The production of ethyl esters for use as biodiesel has many advantages over the production of methyl esters. The former have lower exhaust emissions, and improved properties such as cetane number, cloud point and flash point. Besides, yield values greater than 104 % in reference to the oil, which represents approximately 16 million U$S per year in a 300,000 tons/year plant. In this paper we studied the optimization of a production process of ethyl esters using as raw materials crude and refined sunflower and soybean oils, and refined tallow. Different catalysts, alcohol concentrations, reaction temperature, and reaction in one or two stages, were studied. It was concluded that processes in one stage are not suitable in terms of economic and technological aspects. In contrast, two-step process can be fully adapted to the infrastructure that exists today in most plants in the country, obtaining a biodiesel with excellent quality.
