✦ Synopsis

The supercritical fluid extraction of organics from sun-and air-dried peat was investigated using solvents providing different intermolecular solutesolvent forces. Snyder's classification of selectivity groups indicated that acetone-water mixtures capable of large dipole interactions were more successful than those promoting hydrogen-bonding:

water (proton donor) and methanol-water mixtures (proton acceptor). Neither solvent densities nor Hildebrand solubility parameters were satisfactory for predicting supercritical solvent effectiveness. At slightly subcritical conditions, both the acetone-water mixtures and methanol-water mixtures were good solvents.
