Multiplanar Cyclohexane Rings [PDF]
Nature, 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 ...

Separation of Benzene and Cyclohexane Using Eutectic Solvents with Aromatic Structure
Molecules, 2022 The separation of benzene and cyclohexane is a challenging process in the petrochemical industry, mainly because of their close boiling points. Extractive separation of the benzene-cyclohexane mixture has been shown to be feasible, but it is important to

On the Stable Relative Orientation of Groups Connected by a Carbon-Carbon Single Bond [PDF]
, 1940 Langseth and his co-workers [1] have recently applied the results of essentially incomplete spectroscopic studies of liquid cyclohexane, symmetrical tetrachloroethane, and ethylene deuterobromide to a discussion of the intramolecular forces restricting ...

Crystal structure of 2-cyclohexyl-1,3-thiazolo[4,5-b]pyridine
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title compound, C12H14N2S, the cyclohexane ring adopts a chair conformation with the exocyclic C—C bond in an equatorial orientation. The mean plane through the cyclohexane ring (all atoms) is twisted from the thiazolopyridine ring system (r.m.s ...
