The electrode reaction of the Mn(II)/Mn(Hg) system in acetonitrile and its mixtures with water has been studied. Charge-transfer rate constants, diffusion coefficients and formal potentials were determined. The transfer energies of Mn(II) from water to water+acetonitrile mixtures were calculated, ...
An experimental teratogen.Other experimental reproductive effects.When heated to decomposition or inreaction with water, steam, acid, or acidfumes it produces toxic fumes of CN-, Cl-,and NOx.

Acetonitrile is usually a by-product of the preparation of acrylonitrile by ammoxidation. It can also be prepared by the one-step synthesis at 360°C with acetic acid ammoniation using alumina trioxide as a catalyst. Reaction equation: CH3COOH+NH3[Al2O3]→CH3CN+2H2O ...

The effects of different mixtures of aqueous buffer and acetonitrile on the immobilized preparation were evaluated using a dipeptide synthesis as model reaction. The initial reaction rate at 6-95% of water increased with increasing water content. The maximum yield of peptide had two maxima; the ...
With these immobilized enzymes Bz-Arg-Leu-NH2 dipeptide synthesis was carried out. Iso amylalcohol, tetrahydrofuran and acetonitrile were used as solvents giving the highest yield in the peptide formation reaction. The yield of the peptide was strongly dependent on water content in the reaction ...

Industrially, acetonitrile is a byproduct of the reaction between propylene and ammonia which produces acrylonitrile, so often acetonitrile often contains water, acrylonitrile, ether, ammonia and some other impurities, even hydrolyzed acetic acid and ammonia. The purification method is as below: ...
If released to ambient air, acetonitrile will remain in the vapor phase where it will be degraded through reaction with photochemically produced hydroxyl radicals. The half-life of acetonitrile in ambient air has been estimated to be about 620 days. If released to soil, acetonitrile is expected ...
