colorless liquid, on Ammonia Odor; Steam 45 .32kPa/25 ° C flash point : -8.8 ° C; -72.6 ° C melting point; boiling point of 44.5 ° C; solubility : soluble in ethanol, water, acetone; density : relative density (water = 1) 0.69; relative density (Air = 1) 2.5; Stability : stability; risk Marker 7 (flammable liquids); the main purposes : for the promotion of rubber, chemical reagents and synthetic drugs, pesticides, dyes, etc.

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation, ingestion or absorption through the skin may be lethal. Right eye, skin, and respiratory mucosa have a strong stimulating effect. Inhalation can cause throat, bronchial spasms, dropsy and chemical pneumonia, pulmonary edema and death. Poisoning performance burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

two, toxicology information and environmental behavior

toxicity : it is a high drug category.
acute toxicity : LD₅₀78mg/kg (rat oral)
hazardous characteristics : its steam with the formation of an explosive mixture of air and met the 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 distance, the source cited in a fire burning to return. In case of high fever, increased pressure within containers, cracking and the risk of explosion. A 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 k

5. Environmental standards :
former West Germany (1982) Occupational air 15mg/m3 maximum allowable concentration (Paper) (SIN butylamine)

6. Emergency treatment and disposal methods :
a leakage contingency

leak contaminated areas evacuated personnel to a safe area, not to prohibit access to the contaminated area, cut off the source of fire. Recommended emergency personnel wearing self-contained breathing apparatus to wear general fire protective clothing. Do not direct contact with leakage. To ensure the safety of plugging. Water fog will reduce evaporation, but could not reduce leakage in the restricted space of flammability. Use sand, dry lime or soda ash mixture, and then use non-spark tools to collect and transport the waste disposal sites. We could also use a lot of water washing, Add Water dilution of the wastewater system. If large spills, using a causeway asylum, and then to collect, transfer, recycling or waste processed sound.
waste disposal methods : proposals to control the disposal of incineration. Incinerator emission of nitrogen oxides through the scrubber or high temperature devices removed.

two protective measures

respiratory protection : its possible exposure to vapor, wearing gas masks.
eye protection : Wear protective chemical safety glasses.
physical protection : wear appropriate dress. To minimize direct contact.
hand protection : Wear gloves against chemicals.
other : work site no smoking, eating and drinking. After work, take a shower. For pre-employment and periodic medical examinations.

three, and emergency measures

contact with the skin : the pollution off clothing, immediately rinse with water flow at least 15 minutes.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes. Medical treatment.
INHALED : from the scene to fresh air. To keep the airway patency. Difficult to breathe oxygen. Stop breathing, artificial resuscitation immediately. Medical treatment. Fresh into
: coverage to those who drink large warm water, the symptoms and to seek medical treatment.

fire fighting methods : foam, powder, CO2, sand. Water fire invalid.
