Abstract

Cycloalkanes and their alkyl derivatives represent a significant fraction of jet fuel components. An evaluation of their thermodynamic properties, enthalpies of formation in liquid and gas phases as well as enthalpies of vaporization, was conducted. A combination of available experimental data, up-to-date group-contribution methods, high-level quantum-chemical calculations, and homologous series trends was used to identify outliers and to recommend the most reliable values. Properly corrected, group-contribution approach was found to work well for the enthalpies of vaporization. The performance of group-contribution methods for the enthalpies of formation was found substantially less effective, especially considering notable differences in these properties among stereoisomers. Computationally affordable high-level ab initio results and homologous series trend analysis appears more reliable. The recommended property values for 146 individual compounds and their isomeric mixtures are provided.
