1. Vapor liquid equilibrium Data of non-ideal systems pentane(1)/n-hexane (2)/chloroform (3) and acetone (4) can be determined by "modified Raoult Law" as below: Pi = yi = Yi Xi P; Sat The pressure of pure saturated vapor P, at can be calculated by the Antoine equation, Ln P1 sat = 13.8183-2477.07/(t+ 233.21) Ln P2st 13.8216-2697.55/(t+ 224. 37) Ln P3sat = 6.9033-1163.0/(t+227.4) Ln P4sat = 7.8754 - 1200.5/(t+225.4) The activity coefficient can be calculated using wilson's equation : X₂ Aki Iny, 1-In(YxA,)- ΣxjAj Estimate the saturated vapor pressure above this four-component mixed liquid by composition (1), (2), (3), (4) is respectively 0.2; 0.3; 0.3; 0.2 and the temperature is at 50 OC Literature Data : TOC Л12 A 13 Л 14 A 21 л 23 A 24 A 31 A 32 A 34 Л 41 Л 42 A 43 40 1.244 0.443 1.232 1.325 1.552 1.326 1.432 1.425 1.323 0.455 1.232 1.455 55 1.256 0.464 1.345 1.454 1.645 1.475 1.477 1.233 1.422 0.565 1.345 1.466 60 1.375 0.574 1.345 1.505 1.655 1.545 1.645 2.101 1.002 0.776 1.345 1.567
