Abstract

La presente invención, titulada “Procedimiento para la producción de hidroximetilfurfural a partir de hemicelulosas de maderas de pinos o abetos”, reivindica un proceso aplicable a la obtención de hidroximetilfurfural que consta de las siguientes etapas fundamentales: procesamiento hidrotérmico de muestras de maderas de pinos o abetos (cuyas hemicelulosas están formadas fundamentalmente por glucomanano o galactoglucomanano) para obtener sacáridos hemicelulósicos solubles en agua; etapas intermedias (opcionales) de acondicionamiento de licores hidrotérmicos; conversión de los sacáridos hemicelulósicos en hidroximetilfurfural por deshidratación en medios conteniendo líquidos iónicos (catalizados o en ausencia de catalizador); y recuperación del hidroximetilfurfural del medio de reacción. En el proceso se obtienen furfural y ácido acético como subproductos con valor de mercado.The present invention, entitled "Process for the production of hydroxymethylfurfural from hemicelluloses of pine or fir wood", claims a process applicable to obtaining hydroxymethylfurfural consisting of the following fundamental steps: hydrothermal processing of samples of pine woods or fir trees (whose hemicelluloses are mainly formed by glucomannan or galactoglucomannan) to obtain water-soluble hemicellulosic saccharides; intermediate (optional) stages of conditioning hydrothermal liquors; conversion of hemicellulosic saccharides into hydroxymethylfurfural by dehydration in media containing ionic liquids (catalyzed or in the absence of catalyst); and recovery of hydroxymethylfurfural from the reaction medium. In the process, furfural and acetic acid are obtained as by-products with market value.
