Mini revisión: aplicación de líquidos iónicos en hidrólisis ácida dematerial lignocelulósico para la obtención de azúcares

Abstract

In recent decades, the application of ionic liquids (IL) as pretreatment of residual biomass (BM) before the hydrolysis reaction hasproven to be an efficient system to improve yields towards obtaining monosaccharides. A greater recovery of monosaccharidestranslates into a higher yield in the production of biofuels, which can make this industry profitable. In this context, this bibliographicreview analyzes the physicochemical characteristics, synthesis methods, dissolution conditions with application of variables, suchas: IL: BM weigh ratio, temperature and time. In addition, a comparative assessment of the results of traditional acid hydrolysisprocesses with respect to those obtained with the application of IL is carried out, increasing in most cases their reaction yields.Finally, some recovery and recycling techniques are mentioned, which allow to reduce the costs of the process, so that it iseconomically profitable
