Abstract:

An inverse gas chromatography (IGC) method was used to study the solubility parameters (δ2) and the related thermodynamic properties of polyvinyl alcohol (PVA) that was used for the stationary phase. Totally 5 classes of 18 organic solvent molecules (aliphatic, aromatic hydrocarbons, alcohols, ketones and halohydrocarbons) were used for the probe molecules at 383.15-423.15 K. And the δ2 was compared with the solubility parameter (δT) that was measured by the Hansen solubility parameter (HSP) method. The results showed that the solving ability of PVA decreased in the 5 classes of solvents in the following sequence: ketones > alcohols > halohydrocarbons, aromatic hydrocarbons, aliphatics >alicyclics, and the halohydrocarbons, aromatic hydrocarbons, aliphatics had similar solving abilities. The δ2 increased with the increase of temperature at 383.15-423.15 K. The δ2 of PVA that was derived as 27.69 (J/cm3)0.5 by analytical extrapolation method at room temperature (298.15 K) was consistent with the δT of PVA that was measured as 27.77 (J/cm3)0.5 by the HSP method at room temperature. The determination of solubility parameters and the related thermodynamic parameters can be used as a reference to the application and research of PVA.
