Physical Properties, Reaction Equilibrium and Kinetics

The models that predict the physical properties of the iC4-MeOH-MTBE-inert system are given in tables B.3 and B.4. The reaction equilibrium and kinetics of MTBE synthesis have been subject of intensive research during the last decade (Colombo et ai, 1983  

The vapor fugacity can be written in terms of the fugacity coefficient phi, 

Taking as reference state the pure liquid i at equilibrium temperature T and pressnre P, the liquid phase fugacity /Z can be related to the activity coefficient 7 by, 

Replacing B.4 and B.5 into B.6 leads to the general VXi-equilibrium condition,
