Molecular Formula C₈H₁₈; (CH k3) ₃CCH₂CH (CH₃) ₂
molecular 114.2

colorless, transparent liquid; vapor pressure 5.41kPa; flash point -7 ° C; melting point 107.4 ° C; boiling point of 99.2 ° C; solubility : not soluble in water, soluble in ether, soluble in alcohol, acetone, benzene, chloroform; density : relative density (water = 1) 0.69; the relative density (Air = 1) 3.9; Stability : stability; risk Marker 7 (flash point flammable liquids); the main purposes : in organic synthesis, as solvent and GC sample contrast

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation or oral harmful to our health. Right skin irritation. The goods vapor or mist to the eyes, upper respiratory tract and mucous membrane has a stimulating effect.

two, toxicology information and environmental behavior

toxicity : with a stimulating effect. Is low toxicity category.
acute toxicity : LC₈₀g/m3 × 2 hours (mice inhaled); Mice mouth 0.2ml / only, convulsions, respiratory paralysis, cardiac arrest and death; Inhalation 1g/m3 × 5 minutes and irritation symptoms.

hazardous characteristics : its vapor and air can form explosive mixtures. Case fire, high-heat combustion caused the explosion. Encountered strong oxidants will cause a fire explosion. 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.
combustion (decomposition) products : carbon monoxide, carbon dioxide.

3. Emergency Monitoring Methods :

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. As far as possible, cut off the source of leakage. Preventing access to sewers, flood discharge trench so restrictive space. A small leak : sand, vermiculite or other inert materials to absorb. Open then transported to the place to bury them, evaporation, or incineration. 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 : higher concentration in air, filtered wearing gas masks (half-mask).
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear latex gloves.
other : no smoking scene work. 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 : 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 cooling containers, if possible to move containers from the scene empty Department. At the scene of containers, if any, change from the pressure relief safety devices have voices must evacuate immediately. Extinguishant : foam, powder, CO2, sand. Water fire invalid.
