Molecular Formula C₁₀H₁₆ (mainly)
colorless to pale yellow oily liquid with rosin odor; vapor pressure 2.67kPa/51.4 ° C flash point : 35 ° C; the boiling point of 154 ~ 170 ° C; solubility : do not dissolve in water, soluble in alcohol, chloroform, ether, etc. Most organic solvents; density : relative density (water = 1) 0.85 ~ 0.87; the relative density (Air = 1) 4.84; Stability : stability; risk Marker 7 (YI Burning liquid); the main purposes : as paint solvents, synthetic camphor, adhesives, plastics, such as plasticizers, also used on pharmaceuticals, leather industry

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : Mucocutaneous a stimulating effect on the central nervous certain anesthetic effects and bladder stimulation. Acute poisoning : caused eye and upper respiratory irritation symptoms : tears, coughing; High concentrations of vapor can cause anesthesia, there imbalance and limbs, spastic convulsions, salivation, headache, dizziness, can cause cystitis, sometimes kidney damage. Chronic effects : Prolonged exposure can occur symptoms of respiratory irritation and weakness, drowsiness, headache, dizziness, loss of appetite, etc.. The primary skin irritant is caused skim, drying, redness, can cause allergic dermatitis.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀5760mg/kg (rat oral); LC₅₀12000mg/m36 hours (rat inhalation); 29000mg/m3, 2 hours ( mice inhalation); inhalation 4.2 ~ 5.57g/m3, tears eye irritation, headache, nausea; the person I 150ml death; people percutaneous 0.001%, after contact with the skin drying, redness, and so chapped.
subacute and chronic toxicity : mice Paper 240g/kg × 20 weeks, the minimum concentration of poisoning.

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. In case of high fever, increased pressure within containers, cracking and the risk of explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide.

3. Emergency Monitoring Methods :
turpentine industry's rapid gas chromatography analysis published in the British] / R-useva N. / / Dokl.Bolg.Akad.Nauk.-1985, 38 (10. ) -1343 to 1346 "Analysis of Chemical Abstracts" 1987.10.

4. Laboratory monitoring methods :
Vanilla-spectrophotometry "water quality analysis Daquan" Zhang Hong-tao editor
vanillin method "of harmful substances in the air of Determination" (second edition), Hang Shi-ping editor

5. Environmental standards :
China (TJ36-79) Workshop harmful substances in the air that the maximum allowable concentration of 300 mg/m3
former West Germany (1977) air quality standards 25mg/m3 the former Soviet Union (1975) organics in drinking water maximum allowable concentration 0.2 mg / L
China (to be issued) source water harmful qualitative maximum allowable concentration of 0.2 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 are wearing gas masks, wearing general fire protective clothing. To ensure 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. We could also use non-flammable dispersant wash made of latex, Add Water dilution of the wastewater system. If large spills, using a causeway asylum, and then to collect, transfer, recycling or waste processed sound.

two protective measures

respiratory protection : high concentration environment, should wear protective masks.
eye protection : if necessary, wearing chemical protective safety glasses.
protective clothing : wearing overalls.
hand protection : if necessary, wear protective gloves.
other : no smoking scene work. To avoid long-term repeated exposure.

three, and emergency measures

contact with the skin : contaminated clothing off with soap and water thoroughly washed.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes. Medical treatment.
Inhalation : rapidly from the scene to fresh air. 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, carbon dioxide, dry, sandy soil. Water fire invalid.
