Acetonitrile. H. Robles, in Encyclopedia of Toxicology (Third Edition), 2014. Abstract. Acetonitrile (75-05-8) is a liquid with an etherlike odor. It is a highly polar, volatile organic compound used as a solvent in many different industrial applications. Acetonitrile is metabolized to hydrogen cyanide and can be acutely lethal when absorbed in ...

Acetonitrile. Heriberto Robles, in Encyclopedia of Toxicology (Second Edition), 2005. Uses. Acetonitrile is used in the chemical industry as an intermediary in the synthesis of several chemicals and products such as acetophene, thiamine, acetamidine, and α-naphthaleneacetic acid, nitrogen-containing compounds, acrylic fibers, nitrile rubber, pesticides, pharmaceuticals, …

Acetonitrile is a liquid with an ether-like odor. It is a highly polar, volatile organic compound used as a solvent in many different industrial applications. Acetonitrile is rapidly absorbed from the lungs and intestinal tract. Once absorbed, acetonitrile is metabolized to hydrogen cyanide and it can be acutely lethal when absorbed in high doses.

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 ...

Methanol, acetonitrile, and benzene are widely utilized as organic solvents in the chemical and pharmaceutical industries because of their superior physicochemical characteristics. During drug production, numerous mixtures containing methanol, acetonitrile, and benzene are …

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] .

2005年10月1日 · In this hypothesis, the acetonitrile degradation rate per unit surface area, (− r S), for a second-order kinetic may be written in terms of Langmuir–Hinshelwood model as (16) (− r S) ≡ − 1 S d N AN d t = k AN ″ θ Ox θ AN, where S is the surface area of the photocatalysts, N AN is the acetonitrile moles, t is the time, k AN ″ is ...

2022年2月15日 · Liquid acetonitrile undergoes strong ordering at silica surfaces, as has been studied extensively with both simulations [29–34] and experiments [30,34,35]. In the bulk, acetonitrile is thought to dipole-pair to some extent [36], although there is now evidence the antiparallel molecules take on more of an “octupole-paired” structure [37,38].

1998年9月8日 · All amino acids, diglycine, and acetonitrile (AN) were special reagent grade products from Wako Pure Chemicals. These materials were used without further purification. Hen-egg lysozyme (6 times recrystallized) was purchased from Seikagaku Kogyo (lot E92201). The protein was exhaustively dialyzed against distilled water at 4°C and lyophilized.

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.
