By use of Eq.(1), vapor-liquid equilibria for the following five systems were predicted from binary x-y-t data, and compared with literature values and estimated values by other methods.
logKi = Ai/T + Bi (1)
System A : isopropanol-water-isopropyl ether
System B : methanol-ethanol-water
System C : ethanol-isopropanol-water
System D : methanol-ethanol-isopropanol-water
System E : l-hexadecene-n-tetradecane-naphthalene
These systems are hypothetical reaction systems. For example, the following hypothetical reaction is considered for System A.
2 isopropanol →← isopropyl ether + water
In Eq.(1) Ai is a constant determined by reaction system and component, and Bi is a constant determined from binary x-y-t data for liquid composition at hypothetical conversion 0 and/or 1.
As a conclusion, it was found that the predicted values agree well with the literature values, and that Eq.(1) may be used with nearly equal accuracy to other equations.
