75-31-0; (CH k3) 2CHNH2
& molecular 59.11
nbsp; a colorless and volatile liquid with a fishy smell the ammonia; vapor pressure 29.73kPa/4.5 ° Cflash point : -32 ° C; 101.2 ° C boiling point temperature : 31.7 ° C; Compatibility with water, immiscible in ethanol, ethyl ether; relative density (water = 1) 0.69; the relative density (Air = 1) 2.03; Stability : stability; hazard markers : 7 (low flash point flammable liquids); the main purposes : as solvents, organic synthesis of intermediates, emulsifiers, surface Active Agent, rubber vulcanization accelerator
2. The impact on the environment :
a health hazard
pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation of the vapor or mist goods, a pair of respiratory irritation; Sustained high concentration of respirable cause pulmonary edema. Steam strong eye irritation; Fog liquid or serious damage to the eyes, it can blind to. Skin burns can be addressed. Oral burns digestive tract, a large number of oral caused death.
two, toxicology information and environmental behavior
acute toxicity : LD50820mg/kg (rabbit oral); 380mg/kg (percutaneous rabbit); LC509672mg/m3, 4 hours (rat inhalation )
hazardous characteristics : its 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, nitric oxide.
3. Emergency Monitoring Methods :
4. Laboratory monitoring methods : gas chromatography
"air of harmful substances in the Determination," Hang Shi-ping editor
5. Environmental standards :
former Soviet air workshop harmful substances 1mg/m3
maximum allowable concentration of the former Soviet Union (1975) Harmful Substances in Water maximum allowable concentration of 2 mg / L before
Soviet sewage harmful substances maximum allowable concentration of 6 mg / L
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. Do not direct contact with leakage. As far as possible, cut off the source of leakage. Preventing access to sewers, flood discharge trench so restrictive space. A small leak : sand or other materials Unburning adsorption or absorption. We could also use a lot of water rinse, diluted Add Water 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.
waste disposal methods : control incineration. Incinerator emission of nitrogen oxides through the scrubber or high temperature devices removed.
two protective measures
respiratory protection : its possible exposure to vapor, must wear self-absorption filter respirators (full cover).
eye protection : Respiratory Protection has been protective.
physical protection : wear protective clothing 52,400.
hand protection : Wear gloves Oil-benzene.
other : work site prohibit smoking, eating and drinking. Work to complete, take a shower. Implementation of pre-employment and periodic medical examinations.
three, and emergency measures
contact with the skin : immediately stripped of contaminated clothing, with a large number of mobile wash, at least 15 minutes. Medical treatment.
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. Extinguishing agents : anti-insoluble foam, powder, CO2, sand. Water fire invalid.
