molecular 100.21


colorless volatile liquid; vapor pressure 5.33kPa/22.3 ° C flash point : -4 ° C; -90.5 ° C melting point; the boiling point of 98.5 ° C; solubility : do not dissolve in water , soluble in alcohol, can immiscibility in the ether, chloroform; density : relative density (water = 1) 0.68; the relative density (Air = 1) 3.45; Stability : stability; risk Marker 7 (flash point flammable liquids); the main purposes : for the octane number of standards, solvents, and for organic synthesis, laboratory reagents prepared</sub>

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : Commodities have a narcotic effect and irritation.
acute poisoning : the goods steam inhalation may cause dizziness, nausea, loss of appetite, euphoria and hobbling gait, and even loss of consciousness and throat condition. A pair of mild skin irritation.
chronic effects : Long-term exposure can cause neurasthenic syndrome. A small number of people had mild neutropenia, and dyspepsia.

two, toxicology information and environmental behavior

toxicity : is low toxicity category.
acute toxicity : LD₅₀222mg/kg (mice vein); LC₅₀7500mg/m3, 2 hours (mice inhaled); LC75g/m3 × 2 hours (mice inhaled); inhalation 20.45g/m3 × 15 minutes, nausea, anorexia, gait instability; inhalation 20.45g/m3 × 4 minutes, obviously Vertigo; inhalation 0.93g/m3 stimulate.

hazardous characteristics : flammable vapor and air can form explosive mixtures. Case heat and the fire is burning a risk of explosion. Oxidants contact with a chemical reaction or cause a fire. High-speed impact, mobile, stirring after sparks from static discharge caused combustion 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
(WS/T169-1999, air operations)
Gas Chromatography, "the air of harmful substances Determination" (second edition), Hang Shi-ping editor

5. Environmental standards :
former Soviet air workshop harmful substances maximum allowable concentration function,

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 : activated carbon or other inert materials to absorb. We could also use non-flammable dispersant made of latex, wash, lotion diluted Add to the 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 : higher concentration in air, filtered wearing gas masks (half-mask).
eye protection : Wear protective 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.
