Abstract: | Mutual solubilities and K-values of fish oil fatty acid ethyl esters, prepared from sand launce oil, and sub- and supercritical
carbon dioxide have been measured in an apparatus originally designed for phase equilibrium, density and gasoil ratio measurements
of reservoir fluids. The measurements were performed at pressures from 2 to 22 MPa at temperatures of 283.2, 313.2 and 343.2°K.
Experimental temperatures, pressures, solubilities, K-values and densities are reported. The K-values of ethyl myristate,
palmitate, oleate, eicosapentaenoate and docosahexaenoate are compared with published experimental binary and/or multicomponent
data. Because both vapor and liquid solubilities are reported, such data are applicable in the design of supercritical extraction
plants. |
