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 ...

1991年12月4日 · Acetonitrile is metabolized to hydrogen cyanide and can be acutely lethal when absorbed in high doses. Once metabolized, the mechanism of action is the same as expected for cyanide poisoning. Signs and symptoms of acute acetonitrile intoxication include chest pain, tightness in the chest, nausea, emesis, tachycardia, hypotension, short and ...

2022年2月15日 · (A) An acetonitrile molecule, showing the label and partial charge for each atom type. (B) Representative molecular configuration at T = 298 K for bulk liquid acetonitrile; the red frame indicates the molecular simulation box used in the calculations. (For interpretation of the references to color in this figure legend, the reader is referred ...
Raman spectroscopy study of acetonitrile at low temperature
2021年2月5日 · The low-temperature Raman scattering measurements of liquid acetonitrile were performed from 20 to −196 °C. Selected Raman spectra of acetonitrile in the spectral region of 30–180 cm −1 at different temperatures are presented in Fig. 2 (a). In general, the Raman peaks in the lower wavenumbers region can be associated with lattice vibration.
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.
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] .

Optimization of acetonitrile/water content in hybrid deep eutectic ...
2021年2月1日 · The effects of the amount of co-solvent in DES and the optimal molar ratio between co-solvents have been investigated. When the molar ratio of acetonitrile to water is 4.4:1, hybrid DES shows the best physical properties, including a wide ESW (2.55 V), superior conductivity (15.6 mS cm −1), and low viscosity (5.82 mPa·s). Furthermore, a ...
Structure and dynamics of acetonitrile: Molecular simulation and ...
2022年2月15日 · Acetonitrile (methyl cyanide) is an aprotic organic molecule with a large, permanent dipole moment of 3.92 D [1]. The amphiphilic character of this molecule makes liquid acetonitrile (ACN) a good solvent for many dipolar and non-dipolar solutes. Accordingly, both neat ACN and its binary mixtures with water are commonly used as the solvent ...
