摘　　要：采用甲基吗啉(NMM)和过氧化氢,合成纤维素纤维溶剂氧化甲基吗啉(NMMO)。高效液相色谱跟踪分析反应物和反应产物,优化氧化甲基吗啉的合成条件。研究得到合适的工艺条件:自制复合催化剂C用量为NMM质量的1%,pH7.8,原料配比为n(H2O2)∶n(NMM)=1.1∶1,反应温度70℃,反应时间为6h。氧化甲基吗啉产率可达94%。对合成产物进行了傅立叶红外光谱(FTIR)分析。This article relates to synthesis of N-methylmorpholine-N-oxide as a solvent for manufacture of cellulose fibre by reaction of N-methylmorpholine with Hydrogen peroxide. Reactants and products are analyzed quantitatively by HPLC, factors of synthesis are optimized. The results show that the suitable condition is： quantity of homemade catalyst used 1% of mass of NMM, the values of pH is 7. 8, the molar ratio of H2O2 to NMM is 1.1： 1, the reaction temperature is 70℃, the reaction time is 6 hours. The yield of N-methylmorpholine-N-oxide reaches 94%. At the same time, the molecular structure of production was studied through FTIR analysis.
