The Journal of Chemical Thermodynamics, 1980
Abstract Experimental excess enthalpies and Gibbs free energies of (hydrocarbon + hydrocarbon) and of hydrocarbon + tetrachloromethane) were interpreted in terms of the lattice model. A table of internally consistent lattice constants was obtained for nine types of segments from molecules of tetrachloromethane, n-alkanes, branched alkanes ...

On the Number of Benzenoid Hydrocarbons
Journal of Chemical Information and Computer Sciences, 2002We present a new algorithm which allows a radical increase in the computer enumeration of benzenoids b(h) with h hexagons. We obtain b(h) up to h = 35. We prove that b(h) approximately const.kappa(h), prove the rigorous bounds 4.789 < or = kappa < or = 5.905, and estimate that kappa = 5.16193016(8).

Journal of Canadian Petroleum Technology, 1970
Abstract This paper evaluates the convergence pressure concept for the correlation of K-factors in hydrocarbon systems. It is shown that, even in the case of binary and ternary systems containing non-hydrocarbon components, the concept breaks down and leads to unacceptable errors in the predicted K-factors.

Raman characteristics of hydrocarbon and hydrocarbon inclusions
Science in China Series D: Earth Sciences, 2007The Raman spectrograms of hydrocarbon standard samples show that: (1) the Raman spectrogram of normal paraffin has very strong peaks of methyl and methylene (from 2700 cm−1 to 2970 cm−1); (2) branch methyl has the particular peak of 748 cm−1±; (3) six cyclic has the particular peak of 804 cm−1±; (4) phenyl has two particular peaks of 988 cm−1± and 3058

Inhibition in Hydrocarbon and Hydrocarbon-Aqueous Media
CORROSION 1989, 1989Abstract Different proposed approaches to evaluating the mechanisms of corrosion inhibition of organic inhibitors of diphilic structure that contain both the polar and non-polar fragments are considered, special attention being paid to inhibition in media containing an aqueous electrolyte and a hydrocarbon phase. Critical analysis of the
