colorless liquid; vapor pressure 1.33kPa/8.9 ° C flash point : 12 ° C; the temperature -62 ° C; the boiling point of 113 ~ 114 ° C; solubility : soluble in alcohol, ether, acetone, benzene; density : relative density (water = 1) 1.00; Stability : stability; risk Marker 7 (flammable liquids); the main purposes : for Organic Synthesis</sub>

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation, ingestion or absorption through the skin after hazardous to health. Caused eye, skin, mucous membrane and respiratory stimulation.

two, toxicology information and environmental behavior

hazardous characteristics : its steam with the formation of an explosive mixture of air and met the fire, high-heat combustion caused the explosion. With a strong oxidant can respond. Its vapor is heavier than air, will spread to the lower Department of considerable distance, the source cited in a fire burning to return. In case of high fever, increased pressure within containers, cracking and the risk of explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide, hydrogen fluoride.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography

5. Environmental standards :

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 self-contained breathing apparatus to wear general fire protective clothing. To ensure the safety of plugging. Water fog will reduce evaporation, but could not reduce leakage in the restricted space of flammability. Use sand, dry lime or soda ash mixture, and then use non-spark tools to handle waste disposal sites. We could also use non-flammable dispersant wash made of latex, Add Water dilution of the wastewater system. If large spills, then use causeway asylum collection, transfer, recycling or waste processed sound.

two protective measures

respiratory protection : high concentration environment, should wear protective masks.
eye protection : to use safety masks.
physical protection : wear overalls.
hand protection : if necessary, wearing anti-chemical gloves.
other : no smoking scene work. Work completed, take a bath. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : contaminated clothing off with soap and water thoroughly washed.
eye contact : immediately filed eyelid, with a large number of mobile water thoroughly washed.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. When necessary, respirators. Medical treatment. Fresh into
: full coverage to persons mouthwash, water, as soon as gastric lavage. Medical treatment.

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