Microemulsion breakdown by pervaporation technique: Effect of the alkyl chain length of n-alkanol, a cosurfactant of the microemulsion [PDF]

open access: yes, 2007
Two sets of microemulsions, cyclohexane- and water-rich ones, were prepared with the following n-alkanols as cosurfactants: n-propanol, n-butanol, n-pentanol, and n-hexanol.

Liquid crystalline properties of unsymmetrically substituted phthalocyanines: structural features leading to nematic mesophase materials [PDF]

open access: yes, 2014
A novel homologous series of four 1,4,8,11,15,18-hexakis(pentyl)-22-methyl-25-hydroxyalkylphthalocyanine derivatives with the hydroxyalkyl chain varying from hydroxynonyl through to hydroxydodecyl has been synthesized to investigate the role of the ...

(E)-1,1′-(Diazene-1,2-diyl)bis(cyclohexane-1-carbonitrile)

open access: yesIUCrData, 2017
The whole molecule of the title compound, C14H20N4, is generated by inversion symmetry. The mid-point of the N=N bond is situated on the inversion centre. The conformation about this central N=N bond is E.

Intramolecular Imino Diels-Alder Reaction: Progress toward the Synthesis of Uncialamycin [PDF]

open access: yes, 2009
We herein described an intramolecular imino Diels-Alder reaction promoted with BF3.OEt2/DDQ affording substituted quinolines. Using this procedure, we prepared the chiral quitioline moiety of the uncialamycin, a new enediyne natural ...

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.

Influence of Dielectric Environment upon Isotope Effects onGlycoside Heterolysis: Computational Evaluation and AtomicHessian Analysis [PDF]

open access: yes, 2019
Isotope effects depend upon the polarity of the bulk medium in which a chemical process occurs. Implicit solvent calculations with molecule-shaped cavities show that the equilibrium isotope effect (EIE) for heterolysis of the glycosidic bonds in 5 ...

The Influence of Diethylaniline and Toluene on the Streamer Propagation in Cyclohexane between a Point-Plane Gap under Positive Impulse Voltage Stress

open access: yesEnergies, 2022
Liquid insulation is used in high voltage equipment such as power transformers as both dielectric medium and coolant. Breakdown in liquid insulation tends to be governed either by streamer initiation under more uniform fields, or by streamer propagation ...

Structure and mobility of cyclohexane as a solvent for Trans-Polyisoprene

open access: yes, 2002
Solutions of {\it trans}$-$polyisoprene in cyclohexane are investigated in atomistic detail at different compositions at two different temperatures. We investigate the influence of polymer concentration on the dynamics of the solvent molecules and the ...
