Separation for the Duple Systems of Cyclohexanol,Cyclohexanone

Using the experience of law and the UNIFAC group contribution method to estimate the combination of a series of solvents were screened.And in accordance with a screening of the extractive distillation solvent for the experiments showed that the use of the feasibility of extractive distillation separation.Model parameters through the extractive distillation and vacuum distillation were calculated for each plate.Under the same conditions,the number of theoretical plates of the extractive distillation was approximate to the number of decompression distillation in15 kPa(absolute pressure).
