;
yellow oily liquid; vapor pressure 0.13kPa/29.5 ° C the flash point of 62.8 ° C; the temperature 2.5 ° C; boiling point of 193.1 ° C; solubility : not soluble in water, soluble in alcohol, ether, chloroform ; density : relative density (water = 1) 0.96; the relative density (Air = 1) 4.17; Stability : stability; risk Marker 15 (hazardous materials from the food); the main purposes : as dye intermediates, solvents, Stability set agent Kit

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : performance and toxicity of aniline similar, but weaker than aniline, in contact with skin ulcers may occur. After absorbing lead to the formation of high-iron hemoglobin caused cyanosis. Contact can be nausea, dizziness, headaches and blood effects.

two, toxicology information and environmental behavior

acute toxicity : LD501410mg/kg (rat oral); 1770mg/kg (rabbit percutaneous)
hazardous characteristics : case of fire, heat or contact with oxidants, combustion caused a risk of explosion. Thermal decomposition of the toxic release of nitric oxide gas.
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" (second edition) Hang Shi-ping editor

5. Environmental standards :
former Soviet air workshop harmful substances maximum allowable concentration 0.2mg/m3
the former Soviet Union (1977) neighborhood atmosphere of harmful substances maximum allowable concentration 0.0055mg/m3 (maximum, average day and night)
the former Soviet Union (1975) Water harmful substances maximum allowable concentration of 0.1 mg / L

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 chemical protective clothing. Do not direct contact with leakage, in ensuring the safety of plugging. Water fog will reduce evaporation, but could not reduce leakage in the restricted space of flammability. Use sand or other absorbent non-flammable mixture absorption, then collect and transport the waste to disposal sites. If large spills, using a causeway asylum, and then to collect, transfer, recycling or waste processed sound.
waste disposal method : incineration, burning heaters have combustion chamber after burning stoves emit nitrogen oxides through the scrubber to remove.

two protective measures

respiratory protection : its possible exposure to vapor, wearing gas masks. Emergency rescue or escape, wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
protective clothing : wearing tight sleeve dress, long-barreled boots.
hand protection : Wear rubber gloves.
other : work site no smoking, eating and drinking. Timely changed or washed overalls. Work was not drinking, bathing with warm water. Monitoring toxic. For pre-employment and periodic medical examinations.

three, and emergency measures

contact with the skin : the immediate pollution of clothing off with soap and water thoroughly washed. Attention to hands, feet and other parts of the nail.
eye contact : immediately filed eyelid, with a large number of mobile or saline irrigation water.
Inhalation : rapidly from the scene to fresh air. Difficult to breathe oxygen. Stop breathing, artificial resuscitation immediately. Medical treatment. Fresh into
: coverage to persons mouthwash, water, activated carbon oral after gastric lavage, or give to catharsis. Medical treatment.

fire fighting methods : water mist, foam, carbon dioxide, dry, sandy soil.
