The Chemical Thermodynamic Properties of Hydrocarbons and Related Substances: The Use of n-Heptane as a Reference Substance for Low-Temperature Calorimetry

Description: From Introduction and Summary: "This bulletin presents the results obtained n-heptane by the petroleum thermodynamics laboratory of the Bartlesville, Okla., facility. Detailed results of five investigations are given; selected values if the low-temperature thermal properties are tabulated; and comparisons with results that were obtained in other laboratories are made. The findings of this extensive study will serve to characterize the low-temperature thermal data for over 100 compounds that will be presented in a later bulletin of this series."

Polycyclic-Aromatic-Hydrocarbon-Induced Alterations in the Physio-Chemical Characteristics of Escherechia Coli Dexyribonucleic Acid

Description: Prior to 1965 the interactions of polycyclic aromatic hydrocarbons with DNA (Deoxyribonucleic acid) had been but moderately studied. It was concluded that, although a controversy existed, an apparent interaction occurred between DNA and certain aromatic hydrocarbon molecules and that the interaction was not an artifact of the reaction system.

Infrared spectra of 47 dicyclic hydrocarbons

Description: From Summary: "The infrared spectra are presented for 47 dicyclic hydrocarbons consisting of some alkyldiphenylmethanes, alkyldicyclohexylmethanes, alkylnaphthalenes, alkyltetralins, 1,3-diphenyl-2-alkylpropanes and 1,3-dicyclohexyl-2-alkylpropanes. The physical properties of these highly purified compounds are included for reference purposes."

Synthesis of cyclopropane hydrocarbons from methylcyclopropyl ketone 3: 2-cyclopropyl-1-butene, cis and trans 2-cyclopropyl-2-butene, and 2-cyclopropylbutane

Description: From Summary: "The hydrocarbons - 2-cyclopropyl-1-butene, cis and trans 2-cyclopropyl-2-butene, and 2-cyclopropylbutane - were obtained from methylcyclopropyl ketone by reacting the ketone with ethylmagnesium bromide, dehydrating the resultant methylethylcyclopropylcarbinol to a mixture of olefins from which 2-cyclopropyl-1-butene and cis and trans 2-cyclopropyl-2-butene were isolated, and hydrogenating the olefins to 2-cyclopropylbutane. All four hydrocarbons were obtained in high purity for the first time; their physical constants and infrared spectra are presented."

Aviation Gasoline and its Component Hydrocarbons: Wartime Research (1940-45)

Description: From Scope and Plan: "As the table of contents indicates, the present report summarizes the important data obtained from the research on aviation gasoline during the period 1940-45, exclusive of the data on jet-propulsion fuels. The report is divided into an introduction giving the historical background for the work, two chapters, and an appendix. The first chapter presents the data in a series of 15 tables carefully cross-indexed and supplemented by 19 charts showing the composition of as many straight-run naphthas. The second chapter discusses in general the equipment, procedures, and methods used in the experimental work and is supplemented by illustrations when necessary."

The Chemical Thermodynamic Properties of Hydrocarbons and Related Substances: [Part] 2. Properties of 25 Organic Sulfur Compounds in the Ideal Gas State from O° to 1,000° K

Description: From Abstract: "Tables of chemical thermodynamic properties for the ideal gas state from 0 degrees to 1,000 degrees K are reported for eight alkanethiols, three cycloalkanethiols and arylthiols, six thiaalkanes, two dithiaalkanes, three thiacycloakanes, and three thiophenes. They are based on current physical and thermochemical constants and definitions, reliable vibrational assignments, and the latest insights into molecular structure and energetics."

Infrared-spectrophotometric analysis of binary and ternary mixtures of liquid hydrocarbons

Description: Report presenting an investigation to determine the suitability and precision of a modified, routine-model, infrared spectrophotometer for analyzing binary and ternary mixtures of aircraft-fuel components. Analyses by means of infrared measurements are described for the following hydrocarbon mixtures: 12 known mixtures of 2,2,3-trimethylbutane (triptane) and cyclohexane, 4 known mixtures of triptane and benzene, and 4 known mixtures of triptane, cyclohexane, and benzene.

Activation of hydrocarbons and the octane number

Description: This report presents an examination of the history of research on engine knocking and the various types of fuels used in the investigations of this phenomenon. According to this report, the spontaneous ignition of hydrocarbons doped with oxygen follows the logarithmic law within a certain temperature range, but not above 920 degrees K. Having extended the scope of investigations to prove hydrocarbons, the curves of the mixtures burned by air should then be established by progressive replacement of pure iso-octane with heptane. Pentane was also examined in this report.

Correlation of Physical Properties With Molecular Structure for Some Dicyclic Hydrocarbons Having High Thermal-Energy Release Per Unit Volume

Description: "As part of a program to study the correlation between molecular structure and physical properties of high-density hydrocarbons, the net heats of combustion, melting points, boiling points, densities, and kinematic viscosities of some hydrocarbons in the 2-n-alkylbiphenyl, 1,1-diphenylalkane, diphenylalkane, 1,1-dicyclohexylalkane, and dicyclohexylalkane series are presented" (p. 55).

Vapor-Phase Oxidation and Spontaneous Ignition-Correlation and Effect of Variables

Description: Note presenting the spontaneous ignition temperatures of eight structurally different hydrocarbons, which were correlated with the behavior of the same hydrocarbons toward vapor-phase oxidation. The results indicated that reducing the stoichiometry of a hydrocarbon-oxygen gas mixture to less than unity decreases the extent of oxidation, other conditions remaining unchanged.
