colorless liquid, unpleasant odor; a flash point of -24 ° C; -0 melting point .5 ° C; the boiling point of 62 ~ 67 ° C; solubility : Micro dissolve in water, immiscible in ethanol, ethyl ether; density : relative density (water = 1) 0.80; the relative density (Air = 1) 3.1; Stability : stability; risk Marker 7 (low flash point flammable liquids), 40 (a drug); the main purposes : for organic synthesis intermediates, synthetic rubber < Preparation / P>

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : If inhaled or oral, is hazardous to health. Steam or fog eye and upper respiratory irritation have. Right skin irritation. Contact causing headaches, nausea and vomiting.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀4729mg/kg (rat oral); LC₅₀81696mg/m3, 4 hours (rat inhalation)
dangerous Characteristics : its vapor and air can form explosive mixtures. Fire case, a high fever caused oxidizer combustion hazards. Heating decomposition of toxic smoke. With a strong oxidant can respond. Contact acid and acid fog produces toxic gases. Water, water vapor reaction to the release of toxic or flammable gases. With calcium hypochlorite, calcium hydroxide and dramatic response. Its vapor is heavier than air, will spread to the lower Department of considerable local and met the fire will generate a return to burning. In case of high fever, increased pressure within containers, cracking and the risk of explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur oxides.

3. Emergency Monitoring Methods :
portable gas chromatography

4. Laboratory monitoring methods : gas chromatography
reference to the "Handbook of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industry publishers

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

rapid withdrawal from air leakage personnel to a safe area, and isolation and strict restrictions on access. Cut off the fire source. Recommended emergency personnel wearing respirators-positive pressure self-sufficiency, wearing fire protective clothing. Do not direct contact with leakage. As far as possible, cut off the source of leakage. Preventing access to sewers, flood discharge trench so restrictive space. A small leak : activated carbon or other inert materials to absorb. We could also use a lot of water rinse, diluted Add Water Wastewater System. Large leak : to build a causeway or trenching asylum; Foam coverage, lower vapor disasters. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : concentration in air overweight, they should wear self-absorption filter respirators (full cover). Extension urgent rescue or evacuation situation, it is recommended to wear air respirators.
eye protection : Wear protective safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear gloves Oil-benzene.
other : no smoking scene work. Work to complete, take a shower. Pay attention to personal hygiene.

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 : as far as possible to move containers from the scene empty Department. Water cooling containers to keep the fire until the end of fire. At the scene of containers, if any, change from the pressure relief safety devices have voices must evacuate immediately. Extinguishing agents : anti-insoluble foam, powder, CO2, sand. Water fire invalid.
