“…A detailed evaluation of solvents for the extraction of butyric acid is not available in the literature. Nevertheless, Zigovaǐ et al [6] carried out screening of 14 solvents for the extraction of butyric acid and a tertiary amine in different diluents, C 8 to C 18 alcohols, dibutyl ether, toluene, and vegetable oils. Davinson and Thompson [7] examined the distribution coefficient of butyric acid for oleyl alcohol.…”

“…However, the use of butyric acid or its esters as additives, in particular in the food or cosmetic industries, makes its origin important since consumers prefer natural products (Zigová et al, 1999;Zigová and Šturdik, 2000). A detailed evaluation of solvents for the extraction of butyric acid is not available in the literature (except in Zigová et al, 1996). They screened 14 solvents for the extraction of butyric acid and a tertiary amine in different diluents.…”

-Liquid-liquid equilibrium (LLE) data for the water + butyric acid + decanol ternary system were determined experimentally at temperatures of 298.15, 308.15 and 318.15 K. Complete phase diagrams were obtained by determining the solubility curve and the tie lines. The reliability of the experimental tie line data was confirmed with the Othmer-Tobias correlation. The UNIFAC method was used to predict the phase equilibrium of the system using the interaction parameters for groups CH 3 , CH 2 , COOH, OH and H 2 O determined experimentally. Distribution coefficients and separation factors were evaluated for the immiscibility region.
