CAS No. 61740, Molecular Formula C3H5NO
white crystalline solid, odorless; 0.21kPa vapor pressure (84.5 ° C); Melting Point 84 .5 ° C; the boiling point of 125 ° C / 3.33kPa; solubility : soluble in water, alcohol, ether, acetone, benzene insoluble; density : relative density (water = 1) 1.12; the relative density (Air = 1) 2.45; Stability : stability; risk Marker 15 (poisoned goods); the main purposes : used in the manufacture of water-soluble polymer that is polyacrylamide
2. The impact on the environment :
a health hazard
pathways : inhaled, ingested, percutaneous absorption.
health hazards : the goods with neurotoxicity. May cause drowsiness weary fingers numb and positional tremor, gait disorders, muscular dystrophy, muscle weakness, sweating hands and scaling as contact dermatitis.
two, toxicology information and environmental behavior
toxicity : middle-class drug.
acute toxicity : 150 ~ LD50 120mg/kg (rat oral)
irritation : a rabbit eyes : 5 mg (24 hours), the severe stimulation.
subacute and chronic toxicity : rat food by mouth added 0.02% to 0.04% of the goods, a ~ 6 months, there peripheral nerve axons and myelin membrane degeneration.
Mutagenicity : sister chromatid exchange : rat oral 600mg/kg, 10 days (consecutive). Sperm morphology changes : 100mg/kg mice by intraperitoneal injection.
reproductive toxicity : rat poisoning by mouth lowest dose (TDL0) : 200mg/kg (progesterone 7 ~ 16 days), neonatal rats caused biochemical and metabolic changes. Minimum rat poisoning oral dose (TDL0) : 544mg/kg (nine weeks, male), caused sperm, male fertility index changes and increased mortality after implantation.
cancer : IARC carcinogens comments : Animal positive.
hazardous characteristics : high fever case, the fire or contact with oxidants, cause a fire danger. In case of high fever, polymerization reaction may occur, large exothermic phenomenon of container rupture and explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide.
3. Emergency Monitoring Methods :
4. Laboratory monitoring methods : gas chromatography

5. Environmental standards :
the former Soviet Union (1975) plant health standards 0.3mg/m3
China (to be issued) source water harmful substances maximum allowable concentration 0.0005mg/L
6. Emergency treatment and disposal methods :
a leakage contingency
isolation leakage polluted area, located around the warning signs, the proposed emergency personnel wearing gas masks, chemical protective clothing to wear. Do not spill direct contact with the clean-shovel collection in a dry Clean covered containers, transported to the waste disposal sites. We could also use a lot of water washing, Add Water dilution of the wastewater system. If large spills, recycling or collection of sound waste treatment.
waste disposal method : incineration. Incinerator emission of nitrogen oxides through the scrubber to remove.
two protective measures
respiratory protection : concentration in air overweight, they should wear protective masks. Emergency rescue or escape, wear self-contained breathing apparatus.
eye protection : if necessary, wearing protective glasses.
protective clothes : wear appropriate protective clothing.
hand protection : Wear gloves against chemicals.
other : work site prohibit smoking, eating and drinking. After thorough cleansing. Separate storage of toxic pollution by the clothes, washed reuse. For pre-employment and periodic medical examinations.
three, and emergency measures
contact with the skin : contaminated clothing off with soap and water thoroughly washed.
eye contact : immediately filed eyelid, mobile water rinse.
INHALED : from the scene to fresh air. When necessary, respirators. Medical treatment. Fresh into
: coverage to those who drink large warm water, the symptoms. Medical treatment.
fire fighting methods : carbon dioxide, dry, sandy soil.
