petroleun ether

GB No. 32002
CAS No. 8032-32-4
Molecular Formula


molecular composition of pentane, hexane transparent colorless liquid, coal oil and gas; vapor pressure 53.32kPa/20 ° C flash point <-20 ° C; melting point <-73 ° C; the boiling point of 40 ~ 80 ° C; solubility : not soluble in water, soluble in ethanol, benzene, chloroform, oils, the majority of organic solvents ; density : relative density (water = 1) 0.64 ~ 0.66; the relative density (Air = 1) 2.50; Stability : stability; risk Marker 7 (flammable liquids); the main purposes : mainly as a solvent and Oil extraction with


2. The impact on the environment :
a health hazard


pathways : inhaled, ingested.
health hazards : its vapor or mist to the eyes, mucous membrane irritation and respiratory it. Poisoning performance of a burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Fosavance cause peripheral neuritis. A strong right skin irritation.


two, toxicology information and environmental behavior


acute toxicity : LD5040mg/kg (mice vein); LC503400ppm, 4 hours (rat inhalation)
hazardous characteristics : its vapor and air can form explosive mixtures. Case fire, high-heat combustion caused the explosion. Large from combustion fumes. With a strong oxidant can respond. 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
reference to the "Handbook of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industry publishers


5. Environmental standards :
American plant health standards 100ppm


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 : concentration in air overweight, wearing a gas mask filter type (half-mask).
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear latex gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, take a shower. Pay attention to personal hygiene.


three, and emergency measures


contact with the skin : immediately stripped of contaminated clothing, use soap and water thoroughly washed skin.
eye contact : immediately filed eyelid, with a large number of mobile water or saline thoroughly washed at least 15 minutes. 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
: oral intake of water were found to blues or egg white. 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.
