ABSTRACT

Phase equilibrium for CO2 + 2-phenylethanol and CO2 + 3-methyl-1-butanol was measured. The two alcohols are both major constituents of wine aroma. The experimental apparatus includes a transparent high-pressure cell made of a sapphire cylinder, which allows full visual observation of the inside. Measurements were performed at temperatures of (313.1 and 323.1) K, and pressures from (8 to 24) MPa for the system CO2 + 2- phenylethanol, and pressures from (5 to 10) MPa for the system CO2 + 3-methyl-1-butanol. The experimental results were fitted with the Stryjek - Vera modification of the Peng- Robinson cubic equation of state, using the composition-dependent mixing-rules of Panagiotopoulos and Reid.
