Product Name: Industrial Acetonitrile  
Trade Mark: Sanren Brand  
Alternative Name: Methyl cyanide  
Molecular formula/Structural Formula:
Production Process: The product is a by-product of the once-through direct oxydation process for acrylonitrile, using propylene、ammonia and air as raw material.  
Properties: The product is a colourless liquid with drastic toxicity and aromatic smell. The flash point is 5.56℃(open cup)and the autoignition point 525℃. The explosion limits for the mixture of its vapor and air is between 4.4%~16%(Vol.). There exists 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 and can be polymerized into dimeric polymer and tripolymer.
