摘要
总结了N—甲基吡咯烷酮和苯酚精制的生产情况。与苯酚相比，NMP溶剂精制收率高，产品质量好，对加工稠油具有良好的适应性，通过采取措施，腐蚀问题已基本解决。实践证明，NMP溶剂精制工艺是成熟的。
A review on production of NMP (N-methyl-pyrrolidone) and phenol refining was given. Com-pared with phenol refining, NMP solvent refining has the advantages of higher yield, good productquality and adapability for processing viscous oll. Using a series of measures, the corrosion problemhas been solved basicly, indicating this technique is mature.
