Determination of Hansen Solubility Parameters by Means of Gas-Solid Inverse Gas Chromatography

Determination of the Solubility Parameter of Soybean Oil by Inverse Gas Chromatography

The solubility parameter ofsoybean oil, 62, has been determined by the technique of inverse gas chromatography (IGC). Using soybean oil as the stationary phase, solute retention volumes were precisely determined as a function of temperature using 22 solute probes of varying solubility parameter (6]). Solvent (oil)-solute interaction parameters, X, were also calculated from the solute retention ...

Determination of Solubility Parameters and Thermodynamic Properties in Hydrocarbon-solvent Systems by Gas Chromatography

Gas chromatography used to calculate the specific retention volume of several hydrocarbons in different chromatographic liquid phases (Squalane, Carbowax-400, Carbowax-1500, Carbowax-4000, Amine220, Dinonyl phthalate, Tributyl phosphate and Trixylenyl phosphate). Some thermodynamic parameters, such as enthalpy of sorption and Flory-Huggins parameters relating the interaction between liquid phas...

Revisiting Hansen Solubility Parameters by Including Thermodynamics

The Hansen solubility parameter approach is revisited by implementing the thermodynamics of dissolution and mixing. Hansen's pragmatic approach has earned its spurs in predicting solvents for polymer solutions, but for molecular solutes improvements are needed. By going into the details of entropy and enthalpy, several corrections are suggested that make the methodology thermodynamically sound ...
