colorless liquid; vapor pressure 5.33kPa/13.9 ° C flash point <-7 ° C; -135 ° C melting point; boiling point of 89.8 ° C; solubility : not soluble in water, soluble in ethanol , ether, benzene; density : relative density (water = 1) 0.69 (20 ° C); the relative density (Air = 1) 3.45; Stability : stability; risk Marker 7 (flash point flammable liquids); the main purposes : chromatographic analysis standards for substances used in organic synthesis and
2. The impact on the environment :
a health hazard
pathways : inhaled, ingested.
health hazards : None of this information goods inhalation poisoning. The goods are hydrocarbons, inhaling high concentrations of hydrocarbons vapor can cause mild respiratory irritation, dizziness, euphoria, mental confusion, nausea and breathing difficulties; Inhalation of high concentrations can induce a coma or even death. Liquid into the lungs and may cause aspiration pneumonia or pulmonary edema. High concentrations of steam a mild eye irritation; Liquid eyes can cause temporary redness and pain. A pair of mild skin irritation; Repeated exposure can induce dermatitis. Oral cause nausea, vomiting, abdominal pain and headache.
two, toxicology information and environmental behavior
acute toxicity : 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 : its 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. In the scene, heating containers risk of 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 : Non-flammable dispersant made of latex, wash, lotion diluted Add to the wastewater system. Or in ensuring the security situation, in situ burning. Large leak : to build a causeway or trenching asylum; Scattered wet ice or ice water cooling. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites.
two protective measures
respiratory protection : Most do not need special protection, high concentrations can wear contact since suction filtered gas masks (half-mask).
eye protection : when necessary, wearing chemical 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.
