On the basis of comparative analysis of physical properties (dielectric constant, dipole moment, polarity, and hydrogen bond acceptor/donor ability) of ethanol and DMSO it has been concluded that in aqueou smedia DMSO is amore effective
solvating agent for hydrophobic (nonpolar) pyrene than ethanol.
BTMPPA and RPO[(OH).sub.2] are both acidic chelating extractants but [R.sub.2]PO is an ion pair
solvating agent.
Organic reactions in ionic liquid media have received much attention in the past decade owing to their unique properties, including their negligible vapor pressure, high polarity, highly
solvating, non-coordinating and non-flammable.
A magnetic stirrer agitated the melted paraffin in the column to improve the
solvating of the paraffin in SC-[CO.sub.2].
Wenzel (chemistry, Bates College) describes chiral NMR derivatizing
solvating agents, metal-based reagents and liquid crystals and explains the compounds for which they can be used for analysis.
Supercritical fluids have the
solvating strength of many organic solvents, but have higher diffusivity, lower viscosity and lower surface tension, which are major benefits in chromatography.
1 the equilibrium constants reflect the
solvating ability of donors, the strongest of them shifting the equilibrium most to the left.
Both the alcoholic washing, which replaces water molecules that were
solvating [Cs.sup.+] by less-effective
solvating molecules of ethanol, and the sample beating, which removes the ethanol-solvating shell, enhance the ironer-sphere complexation of [Cs.sup.+] with the permanent negative charges (Sposito 1984; Anderson and Sposito 1991).
to market an advanced vapor degreasing (AVD) system combining a
solvating agent that dissolves contaminants with a rinsing agent to remove the
solvating agent and dissolved soils.
* John DeVido, Aqualon Co., Wilmington, DE, Low-VOC Water-Borne Coatings for Wood Based on Nitrocellulose-Acrylic Latex: Water-borne lacquers based on a solvent-free nitrocellulose-acrylic latex have been formulated at VOC contents of 2.8 lb/gal and less
Solvating plasticizers provide the best clarity.
