 The study examined the dissolution of lignocellulosic biomass in ZnCl2.4H2O and its subsequent precipitation with water for the separation of its main components. Different dissolution times and temperatures were studied, and 24 hours at 70 degrees Celsius was determined to be the optimal choice. Three solids were obtained from the process, which were analyzed using XRD, SEM, NMR, and FTR spectroscopy. Solid I was the undissolved part of the starting material, consisting mostly of lignin, solid II was a cellulose-rich solid with a low portion of hemicellulose, and solid III was primarily composed of lignin. The reactivity of solid I and solid II in a hydrolysis reaction was tested, and a significant improvement in the conversion and yield of sugars was observed compared to untreated samples. Solid II had a high percentage of total reducing sugars, with a selectivity of 78 to 88 percent depending on the starting biomass. This article was authored by Marta Lara Serrano, Daniela M.
