Volumetric property was measured for carbon dioxide + ethyl acetate at T = 313.15 K and pressures to 10 MPa. Saturated pressure was also measured by the synthetic method. The experimental data obtained were correlated with various equations of state.

Vapor + liquid) equilibrium of scent components, coumarin (1-benzopyran-2-one, CAS Registry No. 91-64-5) and vanillin (4-hydroxy-3-methoxybenzaldehyde, CAS Registry No. 121-33-5), in alcohols, ethanol, 1-propanol, and 2-propanol were measured at atmospheric pressure in the dilute composition range of solid components with a recirculation still. Equilibrium compositions were determined with an ultraviolet spectrometer. The activity coefficients of coumarin at infinite dilution in alcohol were almost unity. The activity coefficients at infinite dilution of vanillin in alcohol were less than unity.
