; Narasinga Rao, N., ; Matheson, H., J. Chem. The average relative volatility of benzene to toluene is 2.5. The advantage of using extractive distillation in this separation can be seen from the data presented in Table 1 below. {\displaystyle \alpha } [all data], Chavanne and Simon, 1919 Estimate the molal percent of mixture to be distilled and the composition of the distillate obtained if distillation is carried out by Differential distillation, collecting all the distillate together. Volatile organic compounds (VOCs) are organic chemical compounds that evaporate easily at room temperature. Vapor-Liquid Equilibrium Data, ; Van Winkle, M., The relative volatility of ethyl benzene to styrene is 1.4 and thus 27.5 theoretical plates are required for separation to 99% purity by conventional rectification at total reflux. Chem., 1955, 27, 1510. Currently, special separation processes such as processes extractive distillation is commercially used for this separation. Bur. J. Chem. Govindaswamy, S.; Andiappan, A.N.
