pale yellow powder, no odor; vapor pressure; melting point 200 ° C (decomposition); solubility : water-soluble, soluble ether, ethanol-soluble, chloroform; density : relative density (water = 1) 1.4 ~ 1.45; Stability : stability; risk Marker 8 (flammable solids); the main purposes : for rubber, plastics such as PVC occurred micropores manufacturing microporous plastic

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : the pyrolysis products can enter the toxic fumes of nitrogen oxides. Oral is moderately toxic.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀940mg/kg (rat oral)
hazardous characteristics : flammable and met the fire, high temperature can lead to decomposition and combustion explosion. With alkaline, acid or acid mist contacts will quickly fire. Mixed oxidants and can form explosive mixtures. By friction, impact or vibration can cause a fire or explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide, nitrogen oxides.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Cut off the fire source. Recommended emergency personnel wearing self-contained breathing apparatus, wearing fire protective clothing. Do not direct contact with leakage. Wetting water, the use of non-spark tools collected in a sealed plastic or cardboard barrels were. Recovery or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : its possible exposure to dust, they should wear self-absorption filter respirators. When necessary, air respirators to wear.
eye protection : Wear protective safety glasses.
physical protection : gas-penetrating protective clothing.
hand protection : Wear protective gloves on infiltration.
other : work to complete, take a shower. To maintain good health habits.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin.
eye contact : Did eyelid, mobile or saline irrigation water. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. If breathing stop immediately mouth. Medical treatment. Fresh into
: warm water to drink enough, the symptoms and to seek medical treatment.

fire fighting methods : fire-extinguishing agent : water, sand. Prohibit the use of acid-base fire-extinguishing agent.
