Molecular Formula C5H10O; CH3CH2CH2CH2CHO
colorless liquid ; vapor pressure 3.5kPa/20 ° C flash point -8 ° C; -91.1 ° C melting point; the boiling point of 103 ° C; solubility : Micro-insoluble in water, soluble in alcohol, ether; density : relative density (water = 1) 0.81; relative density (Air = 1) 2.96; Stability : stability; risk Marker 7 (flammable liquids); the main purposes : as spices, rubber accelerator
2. The impact on the environment :
a health hazard
pathways : inhaled, ingested, percutaneous absorption.
health hazards : steam eye and upper respiratory mucosa have a stimulating effect.
two, toxicology information and environmental behavior
acute toxicity : LD503200mg/kg (rat oral); 4857mg/kg (rabbit percutaneous)
hazardous characteristics : flammable vapor and air can form explosive mixtures. Case fire, high-heat combustion caused the explosion. With the oxidizer reaction will be fierce. In case of high fever, can occur polymerization reaction and emit heat and large containers ruptured and caused the 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 :
Liquid-Liquid Extraction and Gas Chromatography "water and wastewater standards test" version : 19, Jiangsu Provincial Environment Monitoring Center
5. Environmental standards :
American plant health standards 175mg/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 a lot of water washing, 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 collection devices. Recovery or shipped to the disposal of waste disposal sites.
two protective measures
respiratory protection : concentration in air overweight, self-priming should wear a gas mask filter type (full cover).
eye protection : Respiratory Protection has been protective.
physical protection : antistatic wear uniforms.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, take a shower. To maintain good health habits.
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, water or 1% sodium thiosulfate solution gastric lavage. Medical treatment.
fire fighting methods : as far as possible to move containers from the scene empty Department. Water cooling containers to keep the fire until the end of fire. At the scene of containers, if any, change from the pressure relief safety devices have voices must evacuate immediately. Extinguishing agents : anti-insoluble foam, powder, CO2, sand.
