Acrylonitrile is an organic compound with the formula CH 2 CHCN and the structure H 2 C=CH−C≡N. It is a colorless, volatile liquid. It has a pungent odor of garlic or onions. [ 4 ]
Values are given in terms of temperature necessary to reach the specified pressure. Valid results within the quoted ranges from most equations are included in the table for comparison. A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
The "(s)" notation indicates temperature of solid/vapor equilibrium. Otherwise the data is temperature of liquid/vapor equilibrium. log 10 of Acetonitrile vapor pressure.
Acrylonitrile is commonly employed as a comonomer with styrene, e.g. acrylonitrile, styrene and acrylate plastics. Labelling of items of clothing with acrylic (see acrylic fiber) means the polymer consists of at least 85% acrylonitrile as the monomer. A typical comonomer is vinyl acetate, which can be solution-spun readily to obtain fibers that ...
Acetonitrile is a byproduct from the manufacture of acrylonitrile by catalytic ammoxidation of propylene. Most is combusted to support the intended process but an estimated several thousand tons are retained for the above-mentioned applications. [15] Production trends for acetonitrile thus generally follow those of acrylonitrile. Acetonitrile ...
This is illustrated in the vapor pressure chart (see right) that shows graphs of the vapor pressures versus temperatures for a variety of liquids. [7] At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure defined as 1 atmosphere, [1] 760 Torr, 101.325 kPa, or 14.69595 psi.
Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the ...
The main industrial route to this nitrile is the hydrogenation of acrylonitrile. It is also prepared by the ammoxidation of propanol (propionaldehyde can also be used instead): [7] CH 3 CH 2 CH 2 OH + O 2 + NH 3 → CH 3 CH 2 C≡N + 3 H 2 O. Propionitrile is a byproduct of the electrodimerisation of acrylonitrile to adiponitrile.
