Email: Hiatt.Mike@epa.gov ; Hobbs, M.E. I have discovered that certain nitrogenous organic compounds will effectively increase the relative volatility of ethyl benzene to styrene and permit the separation of ethyl benzene from styrene by rectification when employed as the agent in extractive distillation. Murphy, N.F. This is a straight line of slope 0.75 On/Vn which crosses the y x diagonal at yn zn+i - 0.95 x. ; Smith, J.M., Binary mixtures of naphthenes and aromatics vapor-liquid equilibrium data, ; Weber, J.H., Dunstan, A.E. and the temperature of the extractive agent as it entered the column was 65 C. After establishing the feed rate of the extractive agent, the heat input to the ethyl benzene and styrene in the stillpot was adjusted to give a total reflux rate of 10-20 ml/min.
