Reformation of cyclohexene-cyclohexane extractive distillation column

Hou Lin,Chun Guocheng,Wu Jimin(Henan Shenma Nylon Chemical Co.,Ltd.,Pingdingshan 467013,China)  
A new style packed column technology and a new process is used to reform the separating column system of cyclohexene.The concentration of cyclohexene is reduced to 4.0% from 6.5% at the top of cyclohexene separating column and the concentration of cyclohexane is reduced to 2.5% from 3.5%~4% at the top of cyclohexene recovery column,while the purity of cyclohexene is raised from 95% to 97% or above.
