摘要
提出了萃取精馏分离正己烷甲基环戊烷体系的混合溶剂N 甲基吡咯烷酮 (NMP) 乙二醇 ,通过色谱筛选和汽液平衡测量两种不同方法对该混合溶剂与几种常用单一溶剂的分离效果进行了分析比较 .结果表明 ,混合溶剂具有一定的优越性 ,这为萃取精馏分离正己烷甲基环戊烷体系的溶剂选择提供了新的思路 .
A mixed solvent of NMP and ethylene glycol was proposed for separating Hexane Methylcyclopentane system with extractive distillation. Mixed solvent and some single component solvents were investigated by chromatography and Vapor Liquid Equilibrium experiment. Investigation showed that mixed solvent might be better solvent in selectivities and solubilities than single component solvents.
