Excess volumes of binary mixtures of vinyl acetate and aromatic hydrocarbons
Excess molar volumes of (vinyl acetate + toluene, or ethylbenzene, or p-xylene, or isopropylbenzene, or butylbenzene, or isobutylbenzene, or mesitylene, or t-butylbenzene), were determined from density measurements at T = 298.15 K using a vibrating-tube densimeter. The excess molar volumes are positive over the whole composition range, and increase with the size of the hydrocarbon. Steric hindrance in these mixtures was investigated in terms of the partial excess molar volumes behaviour. The experimental data were used to determine the binary interaction parameters of the Soave-Redlich-Kwong, (SRK) equation of state for use in multicomponent excess functions calculations.
