Determination of environmentally relevant physical‐chemical properties of some fatty acid esters

Abstract Fat models frequently use input parameters that are defined at environmental conditions. In a recently developed gas‐liquid chromatography method (GC‐VAP), vapor pressures, heats of vaporization, and heat capacity differences (gas‐liquid) of fatty acid esters are determined over a large temperature range that includes environmental temperatures. This method also allows an accurate determination of the normal boiling point temperature of a substance. Literature values of vapor pressure, boiling point temperature, and heat of vaporization at 298.15 K for the chosen esters are all in excellent agreement with those determined with the developed method. Correlations between carbon number and heat of vaporization are high.
