Acrylonitrile may also be oxidized by other atmospheric components such as ozone and oxygen. Very little is known about the nonbiologically mediated transformation of acrylonitrile in water. It is oxidized by strong oxidants such as chlorine used to disinfect water. Acrylonitrile is readily degraded by aerobic microorganisms in water.

Acrylonitrile is a colorless, liquid chemical compound with the formula CH 2 CHCN, mainly produced by the catalytic ammoxidation of propylene. It has a distinct, strong onion or garlic odor. Other names for acrylonitrile are 2-propenenitrile, propenenitrile, cyanoethylene, vinyl …

2011年1月14日 · Acrylonitrile is a colorless chemical mainly produced by the ammoxidation of propylene used as a raw material in the manufacture of plastics, resins, and nitriles. Exposure to acrylonitrile has been shown to cause death and neurological …

2015年8月5日 · Acrylonitrile is metabolized to a lesser extent in humans than in rodents. Acrylonitrile metabolism in humans follows first-order kinetics and acrylonitrile has a half-life of ∼8 h. The elimination of acrylonitrile from the plasma of rats is biphasic, with a half-life of 3.5–5.8 and 50–77 h in the a and b phases, respectively. There are ...

2014年10月1日 · First, acrylonitrile substrate significantly inhibits the enzyme activity of NHase because acrylonitrile is an organic solvent, which likely causes NHase denaturation (Mersinger et al., 2005). At an optimum reaction temperature, the concentration of acrylonitrile should not exceed 60.69 g/L (solubility of acrylonitrile under 293 K). Hence ...

2024年1月18日 · Acrylonitrile (ACN) is among the top 25 chemical intermediates being used for the manufacture of acrylic and modacrylic fibers, polyacrylonitrile (PAN)-based carbon fibers, plastics, rubber, and specialty products, 1, 2 which are feedstocks in clothing, carpeting, hoses, seals, gaskets, etc., as shown in Figure 1.

2025年1月1日 · Acrylonitrile is the classical raw material for the production of resins, synthetic fibers, and carbon fibers and is used as a monomer for manufacturing a number of significant copolymers, including Acrylonitrile styrene acrylate (ASA), ABS, acrylic, modacrylic fibers and other synthetic rubbers such as acrylonitrile butadiene (NBR).

2020年5月1日 · Acrylonitrile constitutes about minimum 85% of acrylic fibers. Acrylic fibers are used in carpets, furniture covers, and winter tricot dresses, and etc. Other acrylonitrile consumers are Tabriz Petrochemical Company and 15-Khordad institution with total annual demand of 10,000 tons for ABS resin production units.

2025年1月10日 · Traditionally, the heterogeneous polymerization of acrylonitrile (AN) generally carried out using aqueous precipitation polymerization with H 2 O as medium. In addition, the academic community has been exploring the polymerization characteristics of AN in other polymerization media, such as acetone [ 17 ], tetrahydrofuran (THF) [ 17 ], mixture ...

2018年9月26日 · These vibrations are typical features of the PAN homopolymer, which consists only of acrylonitrile (AN) monomers [32]. The band at 1736 cm −1 is assigned to the carboxyl stretching vibration (υ C=O). A weak band appearing in the PAN homopolymer spectra is due to the hydrolysis of nitrile groups during the polymerization process [33].
