description Species of the genus Jatropha are considered a viable alternative for commercial production of biodiesel, particularly J. curcas. Recently J. sotoinunyezii species was described, with distribution in Tamaulipas state, but the feasibility for its industrial use remains unknown. The objective of this work was to characterze the quality and yield of the biodiesel obtained from J. sotoinunyezii as compared with the toxic and nontoxic commercial varieties of J. curcas. The oil from both toxic and non-toxic J. curcas as well as J. sotoi-nunye-zii seeds was transesterified to produce biodiesel and its chemical composition (fatty acid methyl esters) by GC-MS was determined. The seeds from J. sotoi-nunyezii had a higher oil yield than those from the toxic and non-toxic J. curcas varieties (43.5 %, 32.5 % and 33.3 % respectively). The biodiesel conversion efficiency was higher in J. sotoi-nunyezii with 87.2 %. The biodiesel obtained from J. sotoi-nunyezii showed a higher amount of insaturated methyl esters, particularly methyl linoleate. This feature influenced the calculated values of iodine value and cetane number that compared with quality standards such as EN 14214, indicate that the J. sotoi- nunyezii biodiesel is more susceptible to oxidation with respect to that of toxic and non-toxic J. curcas. On the other hand, the calcul ted heating value of biodiesel from J. sotoi-nunyezii and toxic and non-toxic J. curcas is similar to that of diesel.

Las especies del género Jatropha se consideran una alternativa viable para la producción comercial de biodiésel, particularmente J. curcas. Recientemente se describió la especie J. sotoi- nunyezii, con distribución en el estado de Tamaulipas, pero se desconoce si es factible aprovecharla industrialmente. El objetivo del presente trabajo fue obtener y caracterizar la calidad y rendimiento del biodiesel obtenido a partir de J. sotoi-nunyezii, comparándolo con las variedades comerciales de J. curcas tóxica y no tóxica. El aceite de semillas de J. curcas tóxica, J. curcas no tóxica y J. sotoi-nunyezii fue transesterificado para producir biodiésel, y se determinó su composición química (ésteres metílicos de ácidos grasos) por CG-EM. Las semillas de J. soto-nunyezii tuvieron mayor contenido de aceite con respecto a las de J. curcas tóxica y no tóxica (43.5 %, 32.5 % y 33.3 % respectivamente). La eficiencia de conversión a biodiésel fue mayor en J. sotoi-nunyezii con un 87.2 %. La composición química del biodiésel de J. sotoi-nunyezii con respecto al de J. curcas (tóxica y no tóxica) mostró mayor concentración de ésteres metílico insaturados, particularmente linoleato de metilo. Esta característica influyó en los valores calculados de los parámetros de calidad, índice de yodo y número de cetano que comparado con normas de calidad como la EN 14214, indican que el biodiésel de J. sotoi-nunyezii es más susceptible a la oxidación con respecto al biodiésel de J. curcas (tóxica y no tóxica). Por otro lado, el valor calculado de la entalpía de combustión del biodiésel de J. sotoi-nunyezii y J. curcas (tóxica y no tóxica) es similar al del diésel, por lo que ambos valores indican que son biocombustibles con alto contenido energético. Esta comparación permitió considerar a J. sotoi-nunyezii como posible especie promisoria para la producción de biocombustibles de segunda generación.  Universidad Autónoma de Tamaulipas 2016-08-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/html application/xml https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/769 10.29059/cienciauat.v11i1.769 CienciaUAT; Vol. 11 No. 1: July-December 2016; 91-100 CienciaUAT; Vol. 11 No. 1: Julio-Diciembre 2016; 91-100 2007-7858 2007-7521 spa https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/769/383 https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/769/506 https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/769/716 Derechos de autor 2016 CienciaUAT
