Two novel and environmentally benign solvent systems, organic acids-enriched high temperature liquid water (HTLW) and NH₃-enriched HTLW, were developed, which can enhance the reaction rate of acid/base-catalyzed organic reactions in HTLW. We investigated the decomposition of fructose in organic acids-enriched HTLW, hydrolysis of cinnamaldehyde and aldol condensation of phenylaldehyde with acetaldehyde in NH₃-enriched HTLW. The experimental results demonstrated that organic acids-enriched or NH₃-enriched HTLW can greatly accelerate acid/base-catalyzed organic reactions in HTLW.
