Reich, R. and Sanhueza, V., 1992. Vapor-liquid equilibria for α-pinene and β-pinene with 1-butanol and 1-pentanol. Fluid Phase Equilibria, 78: 239-248. Low-pressure isothermal vapor-liquid equilibria (VLE) have been measured for binary systems of α-pinene and β-pinene with 1-butanol and 1-pentanol at two temperature levels, and are used towards the determination of a specialized UNIFAC interaction parameter table. A total of four systems were investigated at the temperatures 368.15 and 393.15 K, at pressures below atmospheric. The experiments have been carried out in a Stage and Fischer equilibrium still with circulation of both phases and with special Viton seals. UNIFAC interaction parameters have been calculated for the new main groups “α-Pinene” and “β-Pinene” with the alcohol group, “OH”.
