Abstract

In this work, biodiesel was obtained and characterized from used cooking oil and methanol by means of the transesterification reaction, with the aim of using waste oil (a low-value triglyceride resource) as a raw material and thus contributes to minimizing environmental impact. With the methodology used, biodiesel produced from waste oil shows characteristics like biodiesel obtained from virgin oil, as could be seen when characterizing each of the samples characterized by means of various physicochemical tests and by GC-MS chromatography. The realization of this research project generated relevant information and know-how regarding the methodology for the correct characterization by GC-MS of the main components (FAME) present in the biodiesels produced. Among the FAMEs that were characterized are the methyl octanoic, decanoic and octadecanoic esters. These results confirm that biodiesel obtained from cooking oil is a viable and sustainable alternative. In addition, the analytical characterization by GC-MS provided information on FAME, which facilitates its comparison with quality standards and its possible application in diesel engines. In this way, the study contributes to affirming that the scaling of the methodology proposed here is feasible and could contribute to the development of biofuels in Panama, promoting environmental management within the framework of the circular economy.
