Abstract

3-Acetylpyridine(methyl 3-pyridyl ketone)is one of the important compounds to impart flavor and fragrance in various food products. In this work,the solubility data of 3-acetylpyridine in supercritical carbon dioxide (SC-CO 2)were experimentally measured at several temperatures (313.15 K, 323.15 K, 333.15 K, and 343.15 K) and pressures from 10 MPa to 26 MPa under static mode. The experimental solubilities over the measurement range were correlated using Chrastil and Del Valle and Aguilera density-dependent models while phase equilibrium behavior of the studied system was interpreted by Peng–Robinson equa-tion of state (PR-EoS) incorporated with quadratic and Stryjek–Vera mixing rules. The agreement between the model predictions and experimental solubilities was assessed in respect to root-mean-square deviation (RMSD) and consistency of physical meaning of model parameters. Concerning phase equilibria of the studied supercritical system, PR-EoS incorporated with quadratic mixing rule was superior to PR-EoS incorporated with Stryjek–Vera mixing rule and capable to describe the dependency of adjustable binary interaction parameters with temperature.
