Acrylonitrile, or Cyano-ethylene (CH2=CH-CN), is a colourless inflammable liquid with drastic toxicity and irritation irritating smell; dissolves slightly in water and quite well in common organic solvent. There exists the danger of burning and explosion when it meets with fire, high temperature and oxidants. Acrylonitrile vaporvapour and air can form an explosive mixture with the explosion limits between 3.1%-17%(vol.). The boiling point is 77.3°C, the flash point -5°C and the self-ignition point 481°C.
SECCO will manufacture it by direct oxidation by using propylene, ammonia and air as raw materials, which is the leading technology licensed by BP.
It is used for manufacture of synthetic rubber, synthetic resin, dyestuff and medicine.
Acetonitrile, or methyl cyanide (CH3CN), is a colorlesscolourless liquid with drastic toxicity and aromatic smell; the flash point is 5.56°C (open cup) and the self-ignition point 525°C, the explosion limits of its vaporvapour and air mixture between 4.4%-16%(vol).There exits the danger of burning and explosion, if it encounters fire, high temperature and oxidant. It reacts actively with sulphuric acid, fuming sulphuric acid, chlorosulfonate. It is soluble in water and alcohol .
SECCO will manufacture it as a by- product of acrylonitrile by using propylene, ammonia and air as raw material, which is the leading technology licensed by BP.
It is used as an extraction solvent for butadiene and aliphatic acid, calodorant, non-ferrous metal floating agent. It is also a raw material for aromatizer, medicine and agricultural pesticide.
