AB Butanols can be incorporated as biofuels in gasoline. As a consequence, the thermodynamic behaviour in the blend of the different type of accompanying hydrocarbons (paraffins, cycloparaffins, olefins, aromatics) should be explored. Being a multicomponent mixture the best testing ground for checking prediction is the generation of the ternary systems made up of combinations of representatives of the indicated hydrocarbons two by two with alcohols. This paper reports the isothermal vapour–liquid equilibrium (VLE) at 313.15 K of the two remaining ternaries of an overall comprehensive study involving 1- or 2butanol. A recognized accurate static technique consisting of an isothermal total pressure cell has been used for the measurements (Van Ness apparatus). Data were reduced using Barker’s method together with Wilson equation, as excess Gibbs energy model, enabling the determination of all phase equilibrium properties. Starting from our new data we complete the study by discussing the ternary prediction from four model equations by Wohl, Wilson, NRTL and UNIQUAC commonly used. Parameters fed bytheir constituent binaries reported in previous papers conclude that Wilson model provides the best result in both of our ternary systems.
