*  Aromatic Solvents Market Development and Demand Forecast to 2020 | Global Industry news
The Aromatic solvents market is growing with a considerable rate due to high demand for aromatic solvents from the end users such as ink industry, and paint and coating industry. Development of light aromatic fluids is expected to reduce potential hazards caused by aromatic solvents, resulting in a great opportunity for the aromatics solvent market to grow with a more significant rate in the coming years.. A solvent dissolves a solute in a specific volume depending on temperature, to produce a solution. Mixture of solvent and solute, consisting single phase as all the solute molecules occurs as solvates in it, opposes to split continuous phases in emulsions, suspensions and other types of non solution mixtures. On the basis of nature of solvents, solvents can be categorized as polar and non-polar. Dielectric constant is used to measure the ...

*  Solvent - Simple English Wikipedia, the free encyclopedia
A solvent is a substance, that becomes a solution by dissolving a solid, liquid, or gaseous solute. A solvent is usually a liquid, but can also be a solid or gas. The most common solvent in everyday life is water.. Most other commonly-used solvents are organic (carbon-containing) chemicals. These are called organic solvents. Solvents usually have a low boiling point and evaporate easily or can be removed by distillation, thereby leaving the dissolved substance behind. Solvents should therefore not react chemically with the dissolved compounds - they have to be inert. Solvents can also be used to extract soluble compounds from a mixture, the most common example is the brewing of coffee or tea with hot water. Solvents are usually clear and colorless liquids and many have a characteristic smell. The concentration of a solution ...
*  CO-SOLVENT | Banner Chemicals UK - Global Chemical Supplier
Co-Solvent vapor degreasing is the long term cleaning process of the future.. Normal vapor degreasing uses a single solvent to clean and rinse parts. Because the solvent must be boiled in a single solvent vapor degreasing system only solvent with no flash points can be used.. Solvents with no flash points are found only in chemistries based in Chlorine, Bromine or Fluorine. While all of these can be used in vapor degreasers, they each face serious problems, which can be avoided in a co-solvent system.. Chlorinated solvents all have either environmental issues such as ozone depletion or low-level air pollution in the form of volatile organic compounds (VOCs) or heath issues being suspected carcinogens or reproductive hazards. Some industries such as electronics manufacturing avoid using chlorinated and brominated solvents during the ...
*  Solvent-induced two-photon absorption of a push-pull molecule
Solvent-induced two-photon absorption cross sections are calculated for a push-pull molecule in solutions using both self-consistent reaction field and internal finite field approaches. It is shown analytically and numerically that the results from the two methods can be connected through induced local reaction field factors. The two-photon cross sections of the studied push-pull polyene are found to be rather insensitive to the choice of cavity shape. The solvent dependence of the two-photon absorption displays a pattern different from that of the first hyperpolarizability.. ...

*  Solvent accessibilities in glycyl, alanyl and seryl dipeptides | Biochemical Journal
Theoretical studies on glycyl-alanyl and seryl dipeptides were performed to determine the probable backbone and side-group conformations that are preferred for solvent interaction. By following the method of Lee & Richards [(1971) J. Mol. Biol. 55, 379-400], a solute molecule is represented by a set of interlocking spheres of appropriate van der Waals radii assigned to each atom, and a solvent (water) molecule is rolled along the envelope of the van der Waals surface, and the surface accessible to the solvent molecule, and hence the solvent accessibility for a particular conformation of the solute molecule, is computed. From the calculated solvent accessibilities for various conformations, solvation maps for dipeptides were constructed. These solvation maps suggest that the backbone polar atoms could interact with solvent molecules selectively, depending on the backbone conformation. A conformation in the ...
*  Theoretical study of solvent effects on the decomposition of formic acid over a Co(111) surface
article{cb52f0c6-0700-4b46-948b-c6b9df03eca7, abstract = {,p,Solvent effects on the decomposition of formic acid over a Co(111) surface were studied via density functional theory calculations combined with a continuum implicit solvation model. The solvents used here were water, methanol, and acetone. The adsorption energies of key intermediates, the activation barriers and the rate and equilibrium constants of various elementary reactions in vacuum and in the solvents were obtained. Solvent presences decrease the adsorption energies of species. Formic acid decomposition on the surface goes through HCOO rather than COOH both in vacuum and in the solvents. The most favorable decomposition pathways in vacuum and in acetone are HCOOH → HCOO → HCO → CO. The corresponding rate determining steps are HCOO deoxidation to HCO with activation barriers of 0.78 and 0.76 eV, respectively. In the presences of water and methanol, the ...

*  "Molecularly Imprinted Polymers--New Insights and Strategies" by Yagang Zhang
Solvent programmable polymers (SPPs) were developed based on restricted rotation with the ability to respond and remember the stimuli-induced properties. The SPP was prepared via Ring Opening Metathesis Polymerization (ROMP). The recognition properties of SPPs can be modulated by heating in different solvents. At elevated temperatures, the carboxylic acid recognition groups have free rotation and can switch their relative orientations in response to the solvent. On cooling to room temperature, these solvent-induced changes were saved due to restricted rotation about the Caryl-Nimide bonds. Thus, the orientation of the carboxylic acid groups were maintained even when the imprinting solvent is removed or exchanged. The solvent-induced changes are also reversible, and the binding properties can be modulated by cycling between heating the polymer in a polar and nonpolar solvent. The ...

*  DSpace at EWHA: Solvent effect on the α-effect: Ground-state versus transition-state effects; a combined calorimetric and...
In a study of the solvent effect on the α-effect, second-order rate constants (kNu-) have been determined spectrophotometrically for reactions of a series of substituted phenyl acetates with butan-2,3-dione monoximate (Ox-, α-nucleophile) and p-chlorophenoxide (p-ClPhO-, reference nucleophile) in DMSO-H2O (DMSO = dimethyl sulfoxide) mixtures of varying compositions at 25.0 ± 0.1 °C. The magnitude of the α-effect, kOX-/k p-ClPhO-, increases as the DMSO content in the medium increases up to 40-50 mol %, reaching 500, one of the largest α-effect values, and then decreases on further addition of DMSO, resulting in a bell-shaped α-effect profile regardless of the nature of the substrates. The magnitude of the α-effect is found to be significantly dependent on the substrates (or, more quantitatively, on βnuc). Thus, βnuc is an important predictor of the magnitude of the α-effect. The bell-shaped α-effect profile found in the present system is attributed to the differential change in the ...
*  Solvents - Alfa Aesar
Solvents are substances, mostly in the form of liquid, which can dissolve a solute and form a solution. Solvents can be broadly classified into two types, polar solvents (eg. Water) and non-polar solvents (eg. Hexane) based on their dielectric constant. Polar solvents have a strong dielectric constant. They have one or more electronegative atoms like N or O. Common functional groups present in polar solvents include alcohols, ketones, carboxylic acids and amides.
