Özet
Surface energy analysis of red benzoin (RB) and white benzoin (WB), and the separation power of their isomers, was performed using inverse gas chromatography (IGC). The selectivity coefficients () of the structural isomers of RB and WB at infinite dilution were determined to be between 373.2 and 398.2 K for butyl acetate, butyl alcohol, amyl alcohol, and xylene isomers. IGC measurements were performed at infinite dilution to determine the specific adsorption enthalpies of the probe molecules. Based on the IGC measurements, the acidity constants () and basicity constants () of RB and WB were determined using both the classical Gutmann approach and the Hamieh model. Benzoin gums were found to exhibit acidic characteristics.
