Comments Regarding “Measurement and Modeling of Excess Molar Volume and Excess Enthalpy of n-Tridecane or n-Tetradecane with Decalin by Application of PFP Theory”

Abstract

A polemic is given regarding several of the volumetric properties that Touazi and coworkers reported in their published paper. A critical analysis of the published excess molar volumes for binary decalin + tridecane and decalin + tetradecane mixtures revealed that the values determined at low decalin mole fraction compositions were not consistent with values measured at higher decalin compositions. The analysis further showed that the excess molar volumes for the decalin + tridecane and decalin + tetradecane systems differ significantly from published data reported by independent research groups for binary decalin mixtures containing both smaller (C₅ to C₁₂) and larger (C₁₆) linear alkane molecules.
