Solubility of Hydrocarbons in Acetic Acid
Equilibrium distribution coefficients a = [RH]gas/[RH]sol were measured for solutions of normal, iso-, and cycloalkanes and benzene in 100% acetic acid (AcOH) at 298 K and for methane in H2O-AcOH over the whole range of mixture compositions at 283-328 K. Nonelectrolyte solutions obey the equations log(SA/SW) = a + bV̄NE and (logS)E = LVE/V relating the solubility of the nonelectrolyte (NE) in the acid (SA) to its partial molar volume (V̄NE) and solubility in water (SW) (the first equation) and excess solubility values (logS)E to the molar volume (VE) of the system (the second equation).
