colorless crystalline molecular weight, aromatic odor; vapor pressure 0.13kPa / 53 ° C; the flash point of 94.4 ° C; the temperature of 35.5 ° C; boiling point of 201.8 ° C; solubility : Micro-insoluble in water, soluble in alcohol, ether, chloroform, lye; density : relative density (water = 1) 1.03; phase right density (Air = 1) 3.72; Stability : stability; risk Marker 14 (drugs); the main purposes : for organic synthesis and as microbicides, Fungicide

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : the goods on the skin, mucous membrane and stimulate a strong corrosive effect. Caused damage to multiple organs.
acute poisoning : caused muscle weakness, gastrointestinal symptoms, CNS inhibition, prostration, and the temperature dropped coma, and can lead to pulmonary edema and liver, kidney, pancreas and other organs and ultimately respiratory failure.
chronic effects : may cause gastrointestinal dysfunction, liver and kidney damage and skin rashes.

two, toxicology information and environmental behavior

toxicity : is low toxicity category.
acute toxicity : LD50207mg/kg (rat oral); 301mg/kg (rabbit percutaneous)
carcinogenicity : mouse skin by poisoning the lowest dose (TDL0) : 4800mg/kg (12 weeks, intermittent), the induced positive tumors.
right biodegradable impact : water concentration 16.5mg / L, not acclimated activated sludge nitrification of ammonia nitrogen role reduced by 75%, the concentration of 30 mg / L, fluorescent Pseudomonas the degradation of glucose by inhibition concentrations greater than 1000mg / L when E. coli to the degradation of glucose by inhibition.

hazardous characteristics : case of fire, heat or contact with oxidants, combustion caused a risk of explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide.

3. Emergency Monitoring Methods :
direct inlet gas chromatography

4. Laboratory monitoring methods :

5. Environmental standards :
former Soviet air workshop harmful substances maximum allowable concentration 0.5mg/m3
the former Soviet Union (1978) ambient air concentration of basic safety 0.02mg/m3
the former Soviet Union (1975) Water harmful substances maximum permissible concentrations of 0.004mg / L
the former Soviet Union (1975) sewage discharge standard 0.1 mg / L
olfactory threshold concentration 0.2ppm

6. Emergency treatment and disposal methods :

a leakage contingency

isolation leak contaminated areas, restricting access. Cut off the fire source. Recommended emergency personnel wearing self-contained breathing apparatus to wear protective clothing. Do not direct contact with leakage. A small leak : Dust to avoid using cleaner shovel collection in a dry, clean, covered containers. Large Leak : recycling or collection shipped to the disposal of waste disposal sites.
waste disposal method : incineration.

two protective measures

respiratory protection : air dust concentration exceeding should wear headgear electric powered air-purifying respirators and dust; Its possible exposure to vapor, should wear self-priming filtered gas masks (full cover).
eye protection : Respiratory Protection has been protective.
physical protection : wear protective clothing 52,400.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, thorough cleansing. Separate storage of toxic pollution by the clothes, washed standby. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : immediately stripped of contaminated clothing, glycerin, polyethylene glycol or polyethylene glycol and alcohol mixture (7:3) clearing the area, then water thoroughly cleaned. A large number of mobile or 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
: vegetable oil immediately to drink 15-ml. The symptoms. Medical treatment.

fire fighting methods : firefighters are required to wear gas masks, body wear firefighting suits. Extinguishant : mist of water, foam, dry powder, carbon dioxide, sand.
