Resumo: | ABSTRACT Different classes of solvents such as mineral acids and ionic liquids have proved to be capable of disrupting hydrogen bonds among different polysaccharide chains. Recently, a specific family of proticionic liquids (PILs) has been developed with functionality in various industrial applications, adding to the benefits and advantages of their use, since they are absent of aromatic or halogenated molecular structure, making them structurally free of toxicity. This work aimed to verify the influence of proticionic liquids 2-HDEAS, 2-HEACi, 2-HEAL impregnated in the Prosopis juliflora (mesquite) biomass, through the thermogravimetric analysis of macrocomponents hemicellulose, cellulose and lignin. Tests were performed in a simultaneous thermogravimetric analysis equipment under inert atmosphere, 100 mL/min of nitrogen, and 10 °C/min heating rate. It was verified that all PILs present great potential in the degradation and dissolution of the macrocomponent structure of Prosopis juliflora. |
