Crossover VTSRK equation of state for selected alkane + alkane and CO2 + alkane binary mixtures
Fluid Phase Equilibria, 2016Abstract Accurate predictions of the thermodynamic properties of binary mixtures, especially in the critical region, are essential for many chemical process designs. In this study, based on the predictive crossover volume translation SRK equation of state (VTSRK EoS) presented in previous work, the crossover VTSRK EoS for binary mixtures was ...

Ab initio computations, up to CCSD(T)/CBS on model systems, and MP2/cc-pVTZ and DFT calculations are performed on cation-alkane and cation-alkene complexes, cation = Li(+), Na(+), Be(2+), Mg(2+), Ca(2+), Cu(+) and Zn(2+); alkane = C(n)H2(n+2) (n = 1-10) and C6H12; and alkene = C2H4 and C6H6.

The Ionization of Alkanes [PDF]
Israel Journal of Chemistry, 1983 AbstractAb initio molecular orbital theory has been used to study the ionization of methane, ethane, propane, n‐butane, isobutane, cyclopropane and cyclobutane. For methane radical cation, the preferred structure has C20 symmetry and a pair of long C—H bonds, resembling a complex of CH+2 with H2.

Journal of the American Society for Mass Spectrometry, 2022
Chemical characterization of complex mixtures of large alkanes is critically important for many fields, including petroleomics and the development of renewable transportation fuels. Tandem mass spectrometry is the only analytical method that can be used to characterize such mixtures at the molecular level.

Publisher Summary This chapter examines the characteristic infrared (IR) and Raman group frequencies of alkanes. The characteristic vibrations of alkanes can be categorized as CH motions and skeletal (C—C) vibrations. The vibrations involving CH2 and CH3 stretchings give rise to bands that are strong and characteristic in both IR and Raman spectra ...
