Azodiisobutyronitrile uses
Used as polymerization initiator of monomers such as polyvinyl chlorida, polyvinyl alcohol,polystyrene and polyacrylonitrila; As initiator for polymerization of vinyl chlorida acrylonitrila and other monomers, and also as foaming agent for rubber and plastics.
This product can also be used as vulcanizing agent, pesticide and intermediate of organic synthesis.
Nature
White acicular crystal, white powder crystal when the purity is low. Insoluble in water, soluble in methanol, ethanol, acetone, ether, petroleum ether, toluene, aniline and other organic solvents. In case of high heat, open flame or mixed with oxidant, it is dangerous to cause combustion and explosion through friction and impact. When burned, toxic gases are released. When heated, the property is unstable, gradually decomposes at 40 ° C, releases nitrogen and organic cyanide compounds, which is harmful to the human body, and emits large heat, which can cause an explosion.
Use
Used as an initiator for the polymerization of vinyl chloride, vinyl acetate, acrylonitrile and other monomers, the dosage is 0.04% ~ 0.2%. It can also be used as a blowing agent for rubber and plastics such as polyvinyl chloride, polyurethane, polyvinyl alcohol, acrylonitrile and butadiene copolymers. It can also be used as a vulcanizing agent, pesticide and intermediate in organic synthesis.
