Liquid Structure and Thermodynamics of Alkane Mixtures

Abstract: Spectroscopic investigations and light scattering experiments with saturated, liquid hydrocarbons and their mixtures indicate a specific and distinct influence of the constitution, conformation, and flexibility of the molecule on the structure and macroscopic behavior of such liquids. Orientational order present in pure liquid n-alkanes, for example, characteristically affects the thermodynamic mixing properties, such as the enthalpy of mixing AHM and the entropy of mixing ASM, when these liquids are mixed wit… Show more

“…On the other hand, Heintz and Lichtenthaler [47,50] modified the Prigogine-Flory-Patterson model taking into accounts the effect of short-range order observed for alkanes. They applied an extended theory to the pressure dependence of the excess enthalpy.…”

“…[46]. Probably, the Correlation of Molecular Orientation (CMO) is caused by sterically favoured packing phenomena which brings about the segments closer to one another, and thereby increases the attractive interactions [47]. Thus, non-specific interactions, correlations of orientations between the alkane molecules, and free volume effects must be considered in the description of (alkane + alkane) mixtures.…”

“…The primary structure statistics of linear random polymer chains made up of two different kinds of monomers X and Y is concerncd with the distribution of thermally averaged properties of the macromolecules over an ensemble of base sequences [I -41. By thermal average for a particular primary structbre we mean an average over all configurations determined by the intra-chain two-body and threc-body short range interactions [2]. Such study leads to an understanding of the relationship between the information content given by the number of nucleotides.…”

“…In principle, statistical (thermal) avcragcs for thc size or other properties of a random coil can be computed once the problem of adequately labclling all thc conformations in a given configuration is solved [2]. Nevertheless, it is crucial to show how the thermodynamic quantities are distributed over the ensemble of primary structures, ii problem which is inexistent in the statistics of homogeneous polymers.…”

“…There currently is considerable interest in understanding the molecular-level phenomena associated with the measured macroscopic thermodynamic properties of mixing hydrocarbons with each other (1). The measured thermodynamic functions such as excess enthalpy or volume are a manifestation of interactions at the molecular level.…”
