Acrylonitrile - an overview | ScienceDirect Topics
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 - an overview | ScienceDirect Topics
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 …
Acrylonitrile - an overview | ScienceDirect Topics
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 ...

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 …
Effects and mechanism of acrylonitrile use related toxicity
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).
Technical and economic analysis of acrylonitrile production from ...
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.
Acrylonitrile characterization and high energetic photochemistry at ...
2016年5月15日 · Acrylonitrile (from Aldrich, with a purity ⩾99%) was used after purification by vacuum distillation. Acrylonitrile was vapor deposited at a rate of 6 × 10 −1 mol min −1 on a gold-plated copper surface kept at different temperatures between 20 and 300 K with the help of a cold head cryostat (CTI, model 21) within a high vacuum chamber (ca 10 −
Structure of acrylonitrile as determined by electron diffraction and ...
1970年2月1日 · For example, if one were to compare the r^ distance in acrylonitrile with the /g distance in vinylacetylene, the r(C-C) of acrylonitrile would appear about 0.01 A shorter than that of vinylacetylene- As is shown in Table 4, where both distances are now compared on the same basis, the former distance is nearly equal to, and possibly even ...
