Deep eutectic solvents (DESs) are nontoxic, low vapor pressure, biodegradable, chemically stable and environmentally friendly solvents. Among the various DES solvents we are interested in DES based on choline chloride. Choline chloride acts as a hydrogen bond acceptor (HBA) and combines with other hydrogen bond donors (HBD) such as urea, carboxylic acids, sugars or alcohols to form a low melting eutectic mixture. It affects the physical and chemical properties of DES, such as its melting point. Therefore, in this study, the effects of treatment temperature on the chemical composition change of Quercus mongolica wood by choline chloride based eutectic solvent (1: 2 molar ratio) were investigated. The deep eutectic solvent pretreatment temperature was carried out at 100℃ and 140℃. The yield by all DES treatments decreases with increasing processing time. ChCl/lactic acid showed the lowest yield compared to other DESs. ChCl/urea and ChCl/glycerin showed similar characteristics. The chemical composition of the ChCl/lactic acid eutectic solvent decreased with increasing treatment time, but increased with increasing treatment time at 140℃. ChCl/urea and ChCl/glycerin showed little change of lignin and change of cellulose and hemicellulose at 140℃. The crystallinity of cellulose was slightly higher than that of other eutectic solvents, but it was not affected by the treatment temperature.
