colorless liquid; vapor pressure 0.13kPa/13 ° C flash point : 34 ° C; the temperature -58 ° C; boiling point of 168.2 ° C; solubility : not solvent in water, soluble in ethanol most organic solvents; density : relative density (water = 1) 0.87 relative density (Air = 1) 4.62; Stability : stability; risk Marker 7 (flammable liquids); the main purposes : for organic synthesis, is also used as a solvent

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation, ingestion or absorption through the skin, harmful to the body. Have a stimulating effect.

two, toxicology information and environmental behavior

toxicity : is low toxicity category.
acute toxicity : LD₅₀2240mg/kg (rat oral)

hazardous characteristics : high fever case, the fire can cause a fire explosion. With a strong oxidant can respond. In case of high fever, increased pressure within containers, cracking and the risk of explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
chromatography / mass spectrometry method of France and American EPA524.2
GC "Solid Waste dump Test and Analysis and Evaluation Manual, "the China Environmental Monitoring terminus translated

5. Environmental standards :
olfactory threshold concentration 0.05mg/L

6. Emergency treatment and disposal methods :
a leakage contingency

leak contaminated areas evacuated personnel to a safe area, not to prohibit access to the contaminated area, cut off the source of fire. Recommended emergency personnel wearing gas masks, wearing general fire protective clothing. To ensure the safety of plugging. Water fog can reduce evaporation is not reduced leakage in the restricted space of flammability. Use of activated carbon or other inert materials to absorb and then collect and transport the waste to disposal sites. If large spills, using a causeway asylum, and then to collect, transfer, recycling or waste processed sound.

two protective measures

respiratory protection : high concentration environment, wearing gas masks. Emergency rescue or escape, it is recommended to wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
physical protection : wear appropriate dress.
hand protection : Wear gloves against chemicals. Skin can also use the protective membrane.
other : work site no smoking, eating and drinking. After work, take a shower. To maintain good health habits.

three, and emergency measures

contact with the skin : the pollution off clothing, with a large number of mobile water thoroughly washed.
eye contact : immediately filed eyelid, with a large number of mobile or saline irrigation water.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. Difficult to breathe oxygen. Stop breathing, artificial resuscitation immediately. Medical treatment. Fresh into
: full coverage to persons mouthwash, water, as soon as gastric lavage and medical treatment.

fire fighting methods : foam, powder, CO2, sand. Water fire invalid.
