Six solvents acetonitrile, nitromethane, nitroethane, sulpholane
, propylene carbonate and methylene chloride containing a tetrafluoroborate as the inert electrolyte, were shown to have extensive anodic potential ranges and half wave potential data were reported for a series of hydrocarbons in each of these solvents.
The solubility of propane in sulpholane has been determined at temperatures in the range 298-403 K at pressures up to 17.6 MPa.

Sulpholane is a polar solvent, miscible with water and a good solvent for many compounds.
About 100 [cm.sup.3] of liquid sulpholane was drawn into the cell.
The solubility of propane in sulpholane was determined at temperatures of 298.15 K, 313.15 K, 343.15 K, 373.15 K, and 403.15 K at pressures up to 17.6 MPa.
However, sulpholane decomposes before it reaches its critical temperature.
The calculated mole fraction of propane in the sulpholane phase is in good agreement with the experimental values given in Table 1.
