Resumen
Del proceso de obtención de etanol a partir de bagazo de caña se obtienen residuales ricos en carbohidratos que fueron sometidos a un proceso de neutralización y decoloración utilizando una columna de carbón activado, hasta obtener productos con mayor grado de pureza. Utilizando procedimientos químicos de hidrólisis y derivatización, en combinación con la cromatografía gaseosa acoplada a la espectrometría de masas, junto a la información ofrecida por la espectrometría infrarroja y de resonancia magnética nuclear, nos permitió una caracterización parcial de uno de estos productos, el cual está constituido fundamentalmente por polímeros de xilosa y arabinosa, lo que le confiere a este proceso un valor adicional.

Using chemical procedures of hydrolysis and derivatization in combination with the gaseous coupled chromatography to the spectrometry of mass, beside the information offered by the infrared spectrometry and of magnetic nuclear resonance, you allowed us to a partial characterization of one of these products, that is constituted fundamentally from polymers of xylose and arabinose, that you confer this process an additional value.
