Experimental and theoretical investigations of the phase diagram and the interfacial tension are presented. The theoretical framework was able to predict the phase behavior and the interfacial tension with a high accuracy, where only binary experimental data enter the model parameter. The theory permits the calculation of the concentration profiles across the interface. The profiles show that 1‐hexanol will be enriched, which was expected. In same circumstances a competition between hexylacetate and 1‐hexanol was figured out leading to slight minima in the profile of 1‐hexanol.
