Thermodynamic behavior of inorganic and organic systems with eight and more components

We investigated the partial enthalpy of mixing in the eight component system (Ag-Bi-Cd-Ga-In-Pb-Sn-Zn), calculated the solubility of Anthracene in a seven component organic solvent and studied the proper-ties of n-alkanes with 20 to 42 carbon atoms. In systems with 8 components, we have 28 binary interaction parameters: thus uncertainty in one, two or three parameters affects the calculated values only slightly. In the inorganic system, adding Ag to the seven component systems changes the partial enthalpics at the center of gravity of the components slightly. In the solubility data, one cannot differentiate between two significantly different interaction parameters. From the fusion properties of the n-alkanes and binary phase diagrams, the solidification behavior of diesel fuels could be explained.
