Aqueous solubility and related thermodynamic functions of nonaromatic hydrocarbons as a function of molecular structure
Original language description
The aqueous solubilities of C8 nonaromatic hydrocarbons differing by molecular structure were studied between 274 and 313 K using a dynamic saturation column method. The resulting experimental values had uncertainty of less than 5 per cent, their correlation as a function of temperature allowed to determine the thermodynamic functions characterizing the dissolution process. A combination with the thermodynamic data on pure solutes selected from literature made it possible to calculate the Henry's law constants and water-air partitioning coefficients as well as the thermodynamic functions of hydration. These different data were analyzed with respect to the molecular structure of aqueous hydrocarbons; it was found that a simple group contribution schemeis able to rationalize the evolution of dissolution properties at least with the same precision as a more sophisticated method based on hydration properties.
