colorless liquid, similar pear fruit flavor; vapor pressure 1.33kPa/55.5 ° C flash point : 47 ° C; the temperature -35 ° C; boiling point of 150.2 ° C; solubility : dissolve in water, immiscible organic solvent in the majority; density : relative density (water = 1) 0.82; the relative density (Air = 1) 3.94; Stability : stability; risk Marker 7 (flammable liquids); the main purposes : nitrocellulose used solvents and coatings, inert reaction medium. Spices are used for raw materials</sub>

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : mainly narcotic and stimulating effect. Inhalation of high concentrations of steam depth of anesthesia can be addressed; Right nose, eye irritation strong.

two, toxicology information and environmental behavior

toxicity : is low toxicity category.
acute toxicity : LD₅₀1670mg/kg (rat oral); 12600mg/kg (rabbit percutaneous)
irritation : Rabbits open percutaneous stimulation test : D 0.98mg (24 hours) , mildly stimulating.

hazardous characteristics : flammable and met the fire, heat or contact with oxidants, combustion caused a risk of explosion. 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 :
air : samples of activated carbon adsorption, elution with carbon disulfide, and then analyzed by gas chromatography (NIOSH Law)
GC, in the light "Manual of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industry publishers

5. Environmental standards :
American plant health standards 235mg / 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 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, prevent access to sewers, flood discharge trench so restrictive space. A small leak : with 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. 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 (half-mask).
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear rubber gloves.
other : no smoking scene work. Pay attention to personal hygiene. To avoid long-term repeated exposure.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin.
eye contact : immediately filed eyelid, mobile water or saline thoroughly washed at least 15 minutes. 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 cooling containers, if possible to move containers from the scene empty Department. Extinguishant : foam, carbon dioxide, dry, sandy soil.
