The project is intended to understand the energetics of reactions which occur when fluids interact in their supercritical and near-supercritical states. Heat of mixing (H/sup E/) and heat capacity (C/sub p/) data are obtained for selected binary and ternary fluid mixtures using a calorimetric procedure. Calorimeters have been constructed. These data are used in the evaluation of thermodynamic models based on equations of state which have been modified using appropriate scaling factors. Of particular interest has been the successful modeling of binary systems where the critical temperatures of the two components lie close together, in one case (Freon 12 + propane) 15/sup 0/K apart, and the critical pressures are nearly identical. The modeling was accomplished using H/sup E/ data obtained at temperatures up to 573/sup 0/K and pressures to 12.7 MPa for binary CO/sub 2/-X systems where X = decane, hexane, pentane, ethane, toluene, cyclohexane, or pyridine. In addition, several binary Freon-X mixtures have been investigated where X = 2,3- dimethylbutane, N,N-dimethylacetamide, propane or ethane.
