Saturated-liquid heat capacity calculation of alkanes

Abstract

An empirical model for the calculation of the heat capacity of alkanes is recommended. This model was tested and compared to known models (Luria-Benson and Růžička-Domalski) using 68 sets with 1155 literature experimental heat capacity data of 39 alkanes. The obtained results indicate that the new model is slightly better of the existing models, especially near the critical point.
