Abstract: Environmentally friendly and efficient disposal methods are essential for the utilization of agricultural waste to maximize their conversion into high-value products and minimize the effect on the environment. In this study, an ultrasound-NATDES/DMSO system is engineered to transform corn straw into platform compounds. Meanwhile, relevant reaction parameters, including solvent, catalyst, heating temperature, heating time, and ultrasound, are optimized. In the NATDES (ChCl-OA-SnCl4)/DMSO system, after 40 kHz ultrasonic treatment in the pretreatment stage, most platform compounds are obtained at 140 °C for 1 h, among which the yields of 5-HMF, furfural, pentose, hexose are respectively promoted to 27.54%, 33.64%, 95.63%, 49.45%. This study uses a low-cost and more environmentally friendly disposal method to catalyze corn straw to obtain high-value platform compounds, which would provide a novel strategy to use agricultural wastes such as corn straw.
