white opaque solids, deliquescence easy; vapor pressure 0.13kPa (739 ° C); melting point 318.4 ° C; the boiling point 1390 ° C; solubility : soluble in water, ethanol, glycerol, soluble in acetone; density : relative density (water = 1) 2.12; Stability : stability; risk Marker 20 (alkaline corrosive substances); the main purposes : for the soap industry, oil refining, paper, artificial silk, dyeing, tanning, medicine, organic synthesis

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : the goods have strong incentives and corrosive. Dust or smoke stimulate the eyes and respiratory tract, nasal septum corrosion; Skin and eye contact may cause burns; Coverage can cause gastrointestinal burns mucosal erosion, bleeding and shock.

two, toxicology information and environmental behavior

hazardous characteristics : Goods not burn, water and steam heat large, the formation of corrosive solutions. With acid and the occurrence and exothermic reaction. With corrosion.
combustion (decomposition) product : the possible harmful toxic fumes.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : acid-base titration

5. Environmental standards :
China workshop of harmful substances in the air that the maximum allowable concentration 0.5mg/m3

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, joined to a small number of large water and adjust to neutral, then add the wastewater system. 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.

two protective measures

respiratory protection : if necessary to wear protective masks.
eye protection : Wear protective chemical safety glasses.
protective clothing : wearing overalls (anti-corrosion material).
hand protection : Wear rubber gloves.
other : work, take a shower. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : Immediately wash with water for at least 15 minutes. If it burns, medical care treatment.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes. Or 3% boric acid solution rinse. Medical treatment.
Inhalation : rapidly from the scene to fresh air. When necessary, respirators. Medical treatment. Fresh into
: patients immediately clear when the mouthwash, oral diluted vinegar or lemon juice and medical treatment.

fire fighting methods : mist of water, sand.
