Abstract: N-methylmorpholine oxide (NMMO) was synthesized by reacting N-methylmorpholine (NMM) with hydrogen peroxide (H?O?) in the presence of hexane under catalyst-free and atmospheric pressure conditions at 40~90°C, with simultaneous dehydration. The effects of H?O? dosage, hexane volume, and reaction temperature on the synthesis efficiency were systematically investigated. The optimized process parameters were determined as follows: molar ratio of n(NMM)∶n(H?O?) = 1.0:1.2, hexane volume of 60~70 mL, and reaction temperature of 75°C. Under these conditions, the conversion rate of NMM exceeded 98%, and the yield of NMMO reached over 93%.
