colorless to yellow brown liquid, is not happy odor Vapor Pressure : 0.13kPa/12.1 ° Cflash point : 63.9 ° C7.0 ° C melting point, boiling point, 174.5 ° C; soluble in water, soluble in alcohol, ether, sodium hydroxide solution density 1.24; Stability : stable Adversity risk markers : 15 (hazardous materials) main purposes : for Organic Synthesis
2. The impact on the environment
the material harm to the environment, water and soil can cause pollution, especially on mollusks, fish and mammals will cause serious harm.
a health hazard
pathways : inhaled, ingested, percutaneous absorption.
health hazards : no people were poisoned reported. Exposure to animals after a few minutes after the unrest and for what reason acceleration, followed by weakness, tremors, clonic convulsion, short breath and wrong until the crowds died. The Book of Changes, absorbed through skin.
two, toxicology information and environmental behavior
acute toxicity : LD50670mg/kg (rat oral)
Mutagenicity : sex chromosome loss and separation, hamster lung 800umol / L, respectively.
reproductive toxicity : rat poisoning by mouth lowest dose (TDL0) : 4550mg/kg (70 days before mating / progesterone an ~ 21 days), affecting several piglets fetal death in the middle.
carcinogenicity : mouse skin by poisoning the lowest dose (TDL0) 4800mg/kg, 12 weeks (intermittent), suspected to tumor agent-induced skin tumor.
right biodegradable impact : water concentration of 30 mg / L, fluorescent Pseudomonas the degradation of glucose by inhibition, concentration 400 mg / L, E coli degradation of glucose by inhibition.
hazardous characteristics : case of fire, combustible high fever. Heat generated by the decomposition of toxic corrosive flue gas.
combustion (decomposition) products : carbon monoxide, carbon dioxide, hydrogen chloride.

5. Environmental standards
the former Soviet Union (1978) ambient air concentration of basic safety 0.02mg/m3
air olfactory threshold concentration 0.0005mg/m3
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 self-Pressurized respirators to wear protective clothing. Do not direct contact with leakage. As far as possible, cut off the source of leakage, prevent access to sewers, flood discharge trench so restrictive space. A small leak : sand or other materials Unburning adsorption or absorption. 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. With the transfer pump to tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites.
waste disposal method : incineration. Wastes with a mixture of flammable solvents burning, burning heaters should have after the chamber, the burning furnace of the gaseous emissions through the scrubber to remove harmful ingredients.
two protective measures
respiratory protection : its vapor may come into contact with, they should wear self-absorption filter respirators (half-mask). Emergency rescue or evacuation, air respirator should be worn.
eye protection : Wear protective chemical safety glasses.
physical protection : wear protective overalls on infiltration.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, thorough cleansing. Separate storage of toxic pollution by the clothes, washed standby. Pay attention to personal hygiene.
three, and emergency measures
contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin. Medical treatment.
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 : water mist, foam, carbon dioxide, dry, sandy soil.
