Photolysis of Liquid Cyclohexane and Cyclohexane Solutions in the Vacuum Ultraviolet

The Journal of Chemical Physics, 1968
Liquid cyclohexane and cyclohexane solutions were photolyzed at 1236 and 1470 Å. The products and quantum yields for cyclohexane photolysis at 1470 Å are hydrogen (1.0), cyclohexene (0.94), dicyclohexyl (0.06), ethylene (0.003) and butadiene (0.001).

Conformational analysis of cyclohexanes diastereoisomerism in disubstituted cyclohexanes

Resonance, 2005
The cycloalkanes most commonly found in nature, viz., in some alkaloids, steroids and terpenoids contain six membered rings because they can exist in a completely strain free chair conformation. The fundamental understanding of the conformations of cyclohexane and the structures of molecules containing cyclohexane ring was developed by Derek H R Barton

The structure of cyclohexane, F-, Cl-, Br- and I-cyclohexane

Journal of Molecular Structure, 1995
Abstract The ground state, r0, and the average, r∗ , structures of cyclohexane were determined from the recently reported rotational constants for several isotopic species of cyclohexane. These structures provide a better description of the heavy atom skeleton in cyclohexane than the rs structure and allow an accurate prediction of the ...

VAPOR-PHASE RADIOLYSIS OF CYCLOHEXANE AND MIXTURES OF BENZENE AND CYCLOHEXANE

Canadian Journal of Chemistry, 1964
The vapor-phase radiolysis of cyclohexane and benzene-cyclohexane mixtures has been studied with isotopic tracer techniques using C6D12 and C6D6. Benzene does not quench the molecular detachment of hydrogen, [Formula: see text] but interacts with the second-order processes giving HD in C6D12–C6H12 mixtures.

ChemInform Abstract: Reactions of Methyl Radicals with Cyclohexane and Methyl‐Substituted Cyclohexanes

ChemInform, 1989
The reactions of methyl radicals, generated by the photolysis of acetone, with cyclohexane and a number of methyl-substituted cyclohexanes have been studied. The Arrhenius parameters corresponding to overall hydrogen abstraction have been obtained from experiments in the temperature range 100–200 °C based on the value of the rate constant for ...

A vibrational study of cyclohexane and some of its isotopic derivatives-III. A vibrational analysis of cyclohexane, cyclohexane-d12, cyclohexane-1,1,4,4-d4 and cyclohexane-1,1,2,2,4,4,5,5-d8

Spectrochimica Acta Part A: Molecular Spectroscopy, 1973
Abstract A vibrational analysis has been carried out on cyclohexane, cyclohexane-d12, cyclohexane-1, 1,4,4-d4 and cyclohexane-1,1,2,2,4,4,5,6-d8 utilizing the set of 60 internal coordinates (all 18 bond stretches, all 36 valence angle bends and six CCCC torsional bends) that is compatible with the Snyder and Schachtschneider transferable valence ...

Radiation Chemistry of Cyclohexane: V. Dilute Solutions of Benzene in Cyclohexane

Radiation Research, 1962
In a mixture of cyclohexane and benzene exposed to ionizing radiation, the yields of products derived from cyclohexane are much less than would be expected if the decomposition were proportional to the mole fraction of cyclohexane. This result, one of the most striking in radiation chemistry, was first observed in the yields of hydrogen by Schoepfle ...

Ignition of non-premixed cyclohexane and mono-alkylated cyclohexane flames

Proceedings of the Combustion Institute, 2013
Abstract Ignition temperatures of non-premixed cyclohexane, methylcyclohexane, ethylcyclohexane, n-propylcyclohexane, and n-butylcyclohexane flames were measured in the counterflow configuration at atmospheric pressure, a free-stream fuel/N2 mixture temperature of 373 K, a local strain rate of 120 s−1, and fuel mole fractions ranging from 1% to 10 ...

Dehydrogenation of cyclohexane.

1965
The kinetics and mechanism of the dehydrogenation of cyclohexane to benzene over several supported and unsupported catalysts in the form of pellets and powders was studied in the temperature range of about 200 to 600°C in a flow system. Catalysts used inthe study included several commercial catalysts---platinum on alumina, palladium on alumina, cobalt ...
