Abstract: Based on the results obtained in the investigation for cyclohexane recovery by extractive distillation with single solvent,and the Wsy-1 mixed solvent was experimentally studied.The effects of cyclohexanol concentration in solvent,cyclohexane concentration in feed and solvent-to-feed ratio on relative volatility were investigated. The relative volatility of n-heptane/cyclohexane was increased from 0.661 to 1.11, and that of 2,3-dimethylpentane/cyclohexane increased from 0.84 to 1.21 at the Wsy-1 solvent-to-feed ratio of 7∶1. The cyclohexane purity and recovery were 98.5% and 80%, respectively, when a feed stream consisting of 85% cyclohexane was introduced to the experimental extractive distillation column operating at the reflux ratio of 10.
