Kinetics data for the dimerization of cyclopentadiene at 378, 388, and 398 K in supercritical propane solvent were obtained. The dimerization slows somewhat with increasing density. However, the kinetic solvent effect is small compared to the orders of magnitude changes in solubilities observed in the supercritical region. The selectivity of acridine in an acridine/anthracene mixed solute system significantly increased with a 1% methanol/carbon dioxide solvent relative to pure carbon dioxide. This supports the possibility of separations with supercritical fluids. The decorated lattice-gas has been quite successful in modeling supercritical region binary solution solubilities and infinite dilution partial molar volumes. The ability to describe macroscopic thermodynamic properties by this more fundamentally valid approach is extremely encouraging. 1 fig.
