2,2-Azobisisobutyronitrile CAS NO.78-67-1
Name:2,2-Azobisisobutyronitrile
CAS No.:78-67-1
Appearance: white crystal or powder
Molecular formula: C8H12N4
2,2-Azobisisobutyronitrile is white needle-like crystals, white powder crystals 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, there is a danger of burning and explosion through friction and impact. When burning, releases toxic gas. The property is unstable when heated, and gradually decomposes at 40°C, releasing nitrogen and organic cyanide compounds, which are harmful to the human body and emit a large amount of heat, which can cause an explosion.
use
04%～0.2%。 Used as an initiator in 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 foaming agent for rubbers and plastics such as polyvinyl chloride, polyurethane, polyvinyl alcohol, acrylonitrile and butadiene copolymers. It can also be used as vulcanizing agent, pesticide and intermediate in organic synthesis.
safety
Oral LD5025-30mg/kg for rats, 17.2-25rng/kg for mice. In case of accidental contact with skin and eyes, rinse immediately with running water. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It is strictly forbidden to mix and transport with oxidants, edible chemicals, etc.
Packaging and transportation: 20kg/carton (carton), according to customer needs. Hazard class: Class 4.1 UN code: 3234 Packing group: II
Storage conditions: keep away from light, temperature < 20 ℃.
