“…C"T RAPE brandy fusel oils have been found to consist mainly X of alcohols with boiling points higher than that of ethyl alcohol (7). Analyses by careful fractional distillations of rigorously dried samples have been generally successful in separating all of the components, with the exception of the two isomeric five-carbon alcohols, isoamyl (3-methyl-l-butanol) and active amyl (2-methyl-l-butanol) alcohols (7, 10).…”

Je voudrais parler ici des recherches que j'ai effectuées dans le cadre d'un programme de recherches de l'Organisation australienne de recherches (C.S.I.R.O.). Ce sont des recherches sur la structure, la composition chimique et le rôle de la cire cuticulaire des grains de raisins et des feuilles. Ces recherches ont été effectuées principalement lors de l'étude des problèmes relatifs au séchage des raisins pour la production des raisins. Cependant, l'importance de la cire cuticulaire ne se limite pas seulement au séchage des raisins, car elle concerne aussi l'œnologie et les problèmes de la conservation des raisins de table. Je pense donc que mon exposé peut présenter pour vous un certain intérêt.

“…The first ones were developed in the first half of the 20th century. Penniman et al (1937), through colorimetric methods, Schicktanz et al (1939) using azeotropic distillation, and Ikeda et al (1956) from chromatographic analysis, were able to identify the main alcohols (C2 to C5) present in fusel oil from different sources. Marvel and Hager (1924) and Webb et al (1952) found esters derived from short-chain alcohols, mainly i-amyl alcohol, and some carboxylic acids (C10 to C20).…”

By-products valorization in bio-fuels industry is an important issue for making the global process more efficient, more profitable and closer to the concept of biorefinery. Fusel oil is a by-product of bioethanol production that can be considered as an inexpensive and renewable raw material for manufacturing value-added products. In this work, results in terms of composition and physicochemical properties of six samples of fusel oil from industrial alcohol facilities are presented. Composition of the main components was established by gas chromatography. Complementary techniques, such as headspace solid-phase microextraction and gas chromatography-mass spectrometry (GC-MS), were used for detection of minor components. Fifty-five compounds were identified. Physicochemical properties such as density, acid value, moisture content and true boiling point curves were determined. Results are useful in the conceptual design of separation strategies for recovering higher alcohols, as well as to consider new options of valorization alternatives for fusel oil.Keywords: Fuel ethanol, higher alcohols, GC-MS analysis, solid-phase microextraction, TBP. RESUMENLos subproductos para valorización en la industria de los biocombustibles es un tema importante para alcanzar un proceso global más eficiente, más rentable y más cerca del concepto de biorrefinería. El aceite de fusel es un subproducto de la producción de bioetanol que se puede considerar como una materia prima barata y renovable para la fabricación de productos de valor agregado. En este trabajo se presentan los resultados en términos de composición y de las propiedades físico-químicas de seis muestras de aceite de fusel de las instalaciones industriales de alcohol. La composición de los componentes principales se estableció mediante cromatografía de gases. Técnicas complementarias, como espacio de cabeza, microextracción en fase sólida, y cromatografía de gasesespectrometría de masas (GC-MS), fueron utilizadas para la detección de componentes menores. Se identificaron cincuenta y cinco compuestos. Se determinaron las propiedades físico-químicas, como la densidad, el índice de acidez, el contenido de humedad y las curvas de puntos verdaderos de ebullición. Los resultados son útiles en el diseño conceptual de las estrategias de separación para la recuperación de alcoholes superiores, así como para comprobar las opciones de alternativas de valorización del aceite de fusel Palabras Clave: Etanol-combustible, alcoholes pesados, análisis GC-MS, micro-extracción en fase sólida, TBP.
