“…This may be due to the fact that the miscibility of the ACN in water is affected by the volume (or weight) ratio of these solvents. Such ratios affect intermolecular interactions such as the dipole moment between the CH 3 group of the ACN and the OH group of the water, which in turn affects the solubility of HCB in the mixture [26,27]. The miscibility of ACN À H 2 O is best at volume ratios of 30 -70 and 40 -60, and worst at 10 -90, 60 -40 and 80 -20% (v/v) [29].…”

We studied the direct and indirect electrochemical reduction of hexachlorobenzene (HCB) by cyclic voltammetry in the presence of Co(II)Salen as catalyst in organic and aquo-organic solutions. We also studied the degree of dechlorination of HCB by direct electrolysis under different experimental conditions (i.e., potential, organic-water content, catalyst addition). Product analysis was performed by high-pressure liquid chromatography using a UV detector (HPLC-UV). The system containing the catalyst and water favors the HCB-reduction kinetics and the generation of practically only 1,3-dichlorobenzene, chlorobenzene, and benzene.

“…It is a well known fact that binary AN + W mixtures have an upper critical consolute temperature (UCCT) at 271.81 K (–1.34 °C) that is sensitive to the pressure, to the isotopic composition, and to the presence of solutes . Maroscopically homogeneous mixtures above the UCCT exhibit microheterogeneity over a range of intermediate compositions that becomes narrower as the temperature is increased.…”

Binary liquid mixtures of acetonitrile (AN) and water (W) are widely used as reaction media in such fields of chemistry as physical organic chemistry, reverse phase liquid chromatography, and electrochemistry, among others. Much information on the structure of these systems and the interactions in them has accumulated since the author's often quoted comprehensive 1990 paper, so that a review is merited. Macroscopic physical properties, results from diffraction and spectroscopic studies, theoretical considerations and computer simulations, and results from the use of solute probes all bear on the structure (and less so on the dynamics) of the mixtures. These are discussed in terms of the microheterogeneity that occurs in them at intermediate contents (that leads eventually to liquid-liquid phase separation).

“…The polymer samples were vacuum dried (∼50 °C) and solutions made up gravimetrically. The apparatus and the details of the procedure for determining the cloud points have been described in detail elsewhere 6, 7. The accuracy of the cloud point determination is better than ±0.01 K for the lower branch and ±0.1 K for the upper branch.…”

Cloud point measurements were made for binary systems of polystyrene (PS) þ methyl acetate (MA) and polystyrene (PS) þ selectively deuterated MA: CD 3 COOCH 3 and CH 3 COOCD 3 with three PS samples of M w ¼ 4.0 Â 10 5 , 2.0 Â 10 6 , and 13.2 Â 10 6 . All systems are characterized by the phase diagrams with upper and lower critical temperature. H/D isotope effects on miscibility for both selectively deuterated acetates are very large and appeared to be independent of the site of deuterium substitution.
