Use of inverse gas chromatography to account for the pervaporation performance in the microemulsion breakdown [PDF]

open access: yes, 2005
Mass transfer phenomenon that occurs in the pervaporation process when applied to the microemulsion breakdown, was confirmed by the results of inverse gas chromatography.

(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.

Application of the double optic probe technique to distorted tumbling bubbles in aqueous or organic liquid [PDF]

open access: yes, 2005
The optic probe technique is widely used to investigate bubble reactors. To derive values of bubble local velocities and bubble local sizes, a specific signal treatment is usually applied under severe assumptions for bubble path and shape.

Wormlike reverse micelles in lecithin/bile salt/water mixtures in oil [PDF]

open access: yes, 2017
Knowing the ability of water and bile salts to promote the reverse wormlike micelle growth in lecithin/water or lecithin/bile salt mixtures in oil, this work was aimed at elucidating the association properties of the three solutes lecithin, water and the

Thermophysical properties of binary blends of cyclohexane with some esters [PDF]

open access: yesJournal of the Serbian Chemical Society, 2017
From the densities (ρ) and viscosities (η) measured for three binary blends consisting of methyl acetate (MA), ethyl acetate (EA) and methyl salicylate (MS) over the entire composition range with cyclohexane (CH) at 298.15–318.15 K under atmospheric ...

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 ...

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 ...
