Determination of olive oil–gas and hexadecane–gas partition coefficients, and calculation of the corresponding olive oil–water and hexadecane–water partition coefficients

Abstract

Olive oil–gas partition coefficients, Loil, have been determined for 80 solutes at 310 K using a gas chromatographic method in which olive oil is used as the stationary phase. Combination with other literature values has enabled a list of 140 log Loil values at 310 K to be constructed. Hexadecane–gas partition coefficients, Lhex, have similarly been determined for 140 solutes at 298 K. It is shown that olive oil–water partition coefficients, Poil, calculated indirectly from Loil and Lwater partition coefficients agree quite well with directly determined Poil values. Similarly, hexadecane–water partition coefficients, Phex, obtained from Lhex and Lwater agree with directly determined values. It is suggested that in the case of the two particular solvents, olive oil and hexadecane, mutual miscibility of the two phases is of little consequence, and that Poil and Phex values can conveniently be obtained by combining the respective solvent–gas and water–gas partition coefficients.
