Eckert, C A

High temperature solvents, like ammonia, are being investigated. These solvents are likely to prove more appropriate than lower temperature solvents like carbon dioxide for extraction processes with coal. Accurate comparisons of the solvents will be made when several compounds have been tested. A decorated lattice-gas has been used successfully to model supercritical solubilities and infinite dilution partial molar volumes near the critical point. This is the first time such a model has been extended for correlation with experimental data. Since the model is theoretically sound (exact for dilute solutions) this work is particularly encouraging. 2 figs.
