【摘要】 以色谱仪器进行分析测定正己烷和甲基环戊烷在 7种溶剂中的无限稀释活度系数γ∞ ,确定邻苯二甲酸二丁酯为萃取溶剂 ;采用重整抽余油中 90 #溶剂油在常压下蒸馏、切取 67～ 72℃的馏分为原料 ,用萃取和精馏相结合新工艺进行分离实验 ,得到含量≥ 97 6%的正己烷更多还原

【Abstract】 Seven coefficients (γ ∞) of methyl-cyclohexane and alkane at infinite dilutions were analysed with the chromatograph. Alkane refining using dibutyl-o-phthalate as solvent was studied. Raw material of 67?℃ to 72?℃ oil distillated from 90 # solvent oil which was refined from the reforming lash at normal pressure. Extractive distillation experiments have been performed and alkane (≥97.6%) has been obtained.更多还原
