Multiplanar Cyclohexane Rings [PDF]

open access: bronzeNature, 1938
ON bromination, the isomeric forms of 1-carboxy-4-methylcyclohexane-1-acetic acid (m.p. 173° and 137°)1 furnished monobromo acids, which gave the corresponding hydroxy acids on being heated with aqueous sodium carbonate. Oxidation of the hydroxy acids with alkaline permanganate gave rise, however, to isomeric forms of 4-methylcyclohexane-1: 1 ...

Anaerobic degradation of cyclohexane by sulfate-reducing bacteria from hydrocarbon-contaminated marine sediments

open access: yesFrontiers in Microbiology, 2015
The fate of cyclohexane, often used as a model compound for the biodegradation of cyclic alkanes due to its abundance in crude oils, in anoxic marine sediments has been poorly investigated.

The highly selective oxidation of cyclohexane to cyclohexanone and cyclohexanol over VAlPO4 berlinite by oxygen under atmospheric pressure

open access: yesChemistry Central Journal, 2018
Background The oxidation of cyclohexane under mild conditions occupies an important position in the chemical industry. A few soluble transition metals were widely used as homogeneous catalysts in the industrial oxidation of cyclohexane.

The Radiolysis of Cyclohexane. IV. The Effect of Solutes on the Radiolysis of Liquid Cyclohexane

open access: bronzeNippon kagaku zassi, 1963
The effect of the addition of vanlous solutes, such as iodine, aromatic and olefinic compounds, and acetylene, on the gamma radiolysis of liquid cyclohexane was investigated by measuring the yield of hydrogen and in some cases those of hydrogenated compounds of the solutes.

Synergy of pore size and silanols in an –SVR-type zeolite for efficient dynamic benzene/cyclohexane separation [PDF]

open access: yesNature Communications
The efficient purification of cyclohexane is critical, serving as an essential feedstock to produce resins, nylon fibers and pharmaceutical intermediates. However, efficient purification remains a challenging task due to the similarity of cyclohexane and

Enthalpic and Liquid-Phase Adsorption Study of Toluene–Cyclohexane and Toluene–Hexane Binary Systems on Modified Activated Carbons

open access: yesMolecules, 2021
The liquid-phase adsorption of toluene in cyclohexane and hexane solutions on modified activated carbons was evaluated; the energy involved in the interaction between these solutions and the solids was determined by immersion enthalpies of pure solvents ...

Crystal structure of (+)-(1S,5S,6S,7S,10S,11S,16S)-16-hydroxy-7-(methoxymethoxy)-11,15,18,18-tetramethyl-3,13-dioxo-2,4-dioxatetracyclo[12.3.1.01,5.06,11]octadec-14-en-10-yl benzoate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2021
In the fused tetracyclic system of the title compound, C29H36O9, the five-membered dioxolane ring adopts a twist conformation; the two adjacent C atoms deviate alternately from the mean plane of the other three atoms by −0.252 (6) and 0.340 (6) Å.
