Distribution of butyric acid between water and several solvents. The Journal of Chemical Thermodynamics, 38, 1634–1639. Phase equilibria of liquid (water + butyric acid + oleyl alcohol) ternary system. The presented results show the potential of the Dį/µ ratio in the screening and formulation of solvents in extraction and SLM optimization. Using pure OA as the solvent or diluent is not preferable and a mixture of a low viscosity diluent with the OA concentration below 40 mass % should be used. P dependences towards lower OA concentrations by increasing the BA concentration driving force is in agreement with the Dį/µ ratio dependence. P for SLMs exhibited also a maximum at about 30 mass % and 20 mass % of OA at the BA concentration driving force of 0.12 kmol m−3 and 0.3 kmol m−3, respectively. Dependence of the Dį/µ ratio on the OA concentration showed a maximum at the OA concentration of 15 mass % to 30 mass %. The relationship between the ratio of the distribution coefficient of butyric acid (BA), Dį, and the viscosity of OA-dodecane solvents, µ, as extraction and transport characteristics, and the overall mass-transfer coefficient, K This can be decreased by the application of a less viscous OA diluent, e.g. A disadvantage of OA is its relatively high viscosity of 28.32 mPa s at 25☌. Oleyl alcohol (OA) is frequently used as the solvent or diluent in the extraction of carboxylic acids. Solvent formulation is important in the optimization of the mass-transfer through supported liquid membranes (SLM) in pertraction and membrane extraction.
