Product Name: |
Industrial Vinyl Acetate
 |
|
 |
 |
|
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)  |
