摘要: A novel technique is described for the measurement of partial molal volume at infinite dilution solutes in supercritical fluids. Results are reported five systems from 2/sup 0/C above solvent critical temperature up to 15/sup above, pressures just pressure 350 bars. The solute volumes small and positive high pressures, but very large negative highly compressible near-critical region. results interpreted terms structure intermolecular forces.
