The binary liquid of nitromethane and n-nonane exhibits liquid-liquid equilibrium, LLE. At 90C, one phase has a nitromethane mole fraction of 0.214 and the other
The binary liquid of nitromethane and n-nonane exhibits liquid-liquid equilibrium, LLE. At 90C, one phase has a nitromethane mole fraction of 0.214 and the other phase has an n-nonane mole fraction of 0.0469.
Compute the vapor-liquid-liquid equilibrium VLLE for this system at 90oC.
1. Is the one-parameter Margules equation valid for LLE according to the data given?
2. If Margules one-parameter is not appropriate, use the Van Laar equation. Use the given data to estimate the two parameters.
3. Calculate P* and y1* at the 3-phase equilibrium condition. 4. Calculate and graph the complete phase diagram P-x1-y1
