PROPANE SOLUBILITY IN AQUEOUS MINERAL ACIDS (0-100-PERCENT) - A SIGNIFICANT DIFFERENCE IN THE SOLVATING PROPERTIES OF H2SO4, HNO3 AND H3PO4

Unexpectedly high differences in propane solubility in the systems HNO3-H2O (salting-in), H3PO4-H2O (salting-out) and H2SO4-H2O (salting-out at low H2SO4 concentrations and salting-in at high concentrations) have been revealed, and the data quantitatively interpreted within the framework of the previously suggested equation relating the excess amounts of solubility with the molar volume of a system; the general nature of these equations for systems of this type has been demonstrated.
