Acetonitrile - an overview | ScienceDirect Topics
Acetonitrile is a liquid with an ether-like odor. It is a highly polar, volatile solvent used in many different industrial applications. It is widely used in the pharmaceutical, photographic, chemical and analytical industries. It is useful as an industrial solvent for the separation of olefins, polymers, spinning fibers, and plastics.
Acetonitrile - an overview | ScienceDirect Topics
Acetonitrile is a derivative of acetic acid, usually found in aqueous solution, as a secondary product in obtaining acrylonitrile from propylene ammoxidation, or waste streams in extraction processes, chromatography, etc., where also other compounds are found like methanol, benzene, allyl alcohol among others. The concentration level of organic ...

A new potential model for acetonitrile: Insight into the local ...
2017年5月1日 · Acetonitrile (AN) is a polar aprotic solvent that finds ubiquitous usage in chemical industry, electrochemistry and research activity. Despite its intrinsic hazard of flammability and toxicity the wide use of AN arises from the unique combination of such advantageous properties as wide electrochemical window and low viscosity [1] .
Cold-induced aqueous acetonitrile phase separation: A salt-free …
2017年7月14日 · Cooling a 1:1 (v/v) solution of acetonitrile and water at −16° C is known to result in two clear phases. We will refer to this event as “cold-induced aqueous acetonitrile phase separation (CIPS)”. On a molar basis, acetonitrile is 71.7% and 13.6% in the upper and lower phases, respectively, in our study.

Preferential solvation in mixed solvents. 15. Mixtures of acetonitrile ...
2019年8月1日 · Acetonitrile (ethanenitrile, henceforth denoted as MeCN) is a very useful solvent, but certain processes are carried out advantageously in its completely miscible mixtures with other solvents. In such cases the components of the solvent mixture solvate solutes preferentially [1] , but even without added solutes, the preferential solvation of ...
Photocatalytic oxidation of acetonitrile in gas–solid and …
2005年10月1日 · The present paper deals with acetonitrile photodegradation carried out in both gas–solid and liquid–solid regimes using two commercial polycrystalline TiO 2 catalysts (Merck and Degussa P25). This investigation focused on studying the influence of the reaction medium (liquid or gaseous) on the kinetics and mechanisms of acetonitrile oxidation.
Phenylacetonitrile - an overview | ScienceDirect Topics
Phenylacetonitrile is a chemical compound that plays a key role in reaction mechanisms by undergoing deprotonation to form a carbanion, which then attacks other molecules to yield various products.

Acetonitrile-protein interactions: amino acid solubility and ...
1998年9月8日 · The solubility of amino acids and the preferential solvent interaction of hen-egg lysozyme in acetonitrile (AN)-water mixtures (<60 w/v% AN) were investigated by means of densimetric and refractometric methods at 25°C. The free energy of transfer from water to aqueous AN was negative for most nonpolar side-chains of amino acids and positive ...
