| titleOfInvention | Method for separating and producing cyclohexene |
| abstract | There is provided a method for separating cyclohexene comprising the steps of: (a) separating a mixed solution containing cyclohexene, cyclohexane, and benzene by distillation using N,N-dimethylacetamide as an extractant; and (b) feeding at least a portion of a first bottom liquid obtained by separating cyclohexene, cyclohexane, and benzene from the mixed solution in the step (a) to an extractant purification column, withdrawing an azeotrope of cyclohexyl acetate and N,N-dimethylacetamide from a top of the extractant purification column to an outside of a system, and recycling a second bottom liquid of the extractant purification column to the step (a). |
