Product Name:
|
Industrial Vinyl Acetate Â
|
|
Â
|
Â
|
|
Production Process:
|
Vinyl acetate is produced from ethylene and acetic
acid by vapor phase palladium-gold catalytic
oxidation and rectification processes. Â
|
|
Properties:
|
Colorless and transparent liquid with aromatic
smell. Flash point: *8℃, density: 0.**2 g/cm3,
slightly soluble in water, soluble in most organic
solvents, easily react by addition with chlorine,
bromine and ozone. By the action of heat light,
peroxide and catalyst, free radical polymerization
will take place. Category 3 dangerous good, low
flash point inflammable liquid (originally class 1
inflammable liquid), explosion limit:
2.6～ *3.4%(v/v) Â
