CAS No. 123-92-2
Molecular Formula C7H14O2; CH3COO (CH2) 2CH (CH3) < SUB>2
transparent colorless liquid, similar to the smell of bananas; vapor pressure 0.7kPa/25 ° C flash point : 25 ° C; temperature -78 ° C the boiling point of 143 ° C; solubility : do not dissolve in water, immiscible in ethanol, ethyl ether, benzene, ethyl acetate and carbon disulfide majority of organic solvents; density : relative density (water = 1) 0.88; the relative density (Air = 1) 4. 5; Stability : stability; risk Marker 7 (flammable liquids); the main purposes : as solvents, and used to flavor, tanning, rayon, film processing and textile industries
2. The impact on the environment :
a health hazard
pathways : inhaled, ingested, percutaneous absorption.
health hazards : steam eye and upper respiratory mucosa irritation. Contacts have a narcotic effect after coughing, lightheadedness, fatigue, limited burning sensation. High concentration, there were dizziness, fever feelings. Pulse rate, heart palpitations, headache, tinnitus, tremor, nausea and loss of appetite. Drying can cause skin, dermatitis, eczema.
two, toxicology information and environmental behavior
toxicity : is low toxicity category.
acute toxicity : LD5016600mg/kg (rat oral); Inhalation × 27000 ~ 53000mg/m3 short, eyes, nose to the mildly stimulating; Inhalation 5000mg/m3 × 30 minutes, the nose jets stimulation, and weak, headache, lightheadedness.
irritation : a rabbit eyes : 500mg (24 hours), moderate stimulus. Rabbits open percutaneous stimulation test : 500mg, a mild irritant.
subacute and chronic toxicity : rabbit inhalation 26000mg/m3, 4 hours / day, 40 days, anemia, hyperglycemia. Inhalation 10000mg/m3 cats, six hours / day, six days, breathing frequency, urinary protein positive.
hazardous characteristics : flammable vapor and air can form explosive mixtures. Case fire, high-heat combustion caused the explosion. With a strong oxidant can respond. 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. Corrosive.
combustion (decomposition) products : carbon monoxide, carbon dioxide.
3. Emergency Monitoring Methods :
4. Laboratory monitoring methods :
hydroxamic acid "chemical substances harmful air Determination," the chemical industry publishers
5. Environmental standards :
former Soviet air workshop harmful substances maximum allowable concentration 200mg/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. As far as possible, cut off the source of leakage, prevent 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, should wear self-priming filtered gas masks. When necessary, air respirators to wear.
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear gloves Oil-benzene.
other : work site no smoking, eating and drinking. Work to complete, take a shower. Pay attention to personal hygiene.
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. Extinguishant : foam, carbon dioxide, dry, sandy soil.
