3. Benzene, an organic compound, is the simplest aromatic hydrocarbon.   Its chemical formula is C ₆ H ₆ .   At room temperature it is a colorless transparent liquid that is sweet, combustible and carcinogenic.   It is slightly soluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. Benzene is a basic raw material of petrochemical industry.

nature
At room temperature and pressure, it is a colorless transparent volatile liquid. Volatile, can be miscible with ethanol, ether, acetone, chloroform, glacial acetic acid, carbon disulfide, carbon tetrachloride and oil and other organic solvents. Soluble in water: 23.5℃, 0.188%cw/w). Benzene is a compound that does not break down easily. Its vapor can form an explosive mixture with air. Encountering high heat or open flame is extremely easy to cause combustion and explosion. Easy to generate and accumulate static electricity. Intense reaction in contact with oxidant.

preparation
After the industrial benzene is continuously washed with concentrated sulfuric acid to remove the content of thiophene, it is washed with water and 5% sodium hydroxide solution, dried with anhydrous calcium chloride, and the supernatant can be distilled.

use
A standard sample for the determination of refractive index. It can be used as a solvent and cleaning agent for precision optical instruments, electronics industry, organic synthesis, etc.

security
The oral LDso of adult rats was 3.8mL/kg. It is a carcinogen. High concentration of benzene has an anesthetic effect on the central nervous system, causing acute poisoning. Long-term exposure to benzene has damage to the hematopoietic system, causing chronic poisoning. Keep away from fire and heat. The temperature of the reservoir should not exceed 30℃. Keep container sealed. It should be stored separately from oxidants and edible chemicals, and should not be mixed.

1. Applications:

Benzene is used mainly as an intermediate to make other chemicals. it is primarily used in the manufacture of nylon fibers, which are processed into textiles and engineering plastics. Smaller amounts of benzene are used to make some types of rubbers, lubricants, dyes, detergents, and pesticides.

As a gasoline (petrol) additive, benzene increases the octane rating and reduces knocking.

1. Used as an important raw material for synthetic dyes, synthetic rubber, synthetic resins, synthetic fibers, synthetic grains, plastics, medicine, pesticides, photographic film and petrochemical products. This product has good solubility, so it is widely used as adhesives and industrial solvents such as: varnish, nitro fiber paint thinner, paint remover, lubricating oil, grease, wax, celluloid, resin, artificial leather and other solvents.
    2. Standard sample for measuring refractive index. It can be used as a solvent and cleaning agent for precision optical instruments, electronics industry, organic synthesis, etc.
      3. Used as an analytical reagent. If used as solvent, chromatographic analysis of standard substances.
      4. Cosmetic solvents. It is mainly used as a thinner for cosmetics such as nail polish to accelerate drying and hardening, and to improve the solubility of skin film components such as resins.
      5. Used as a solvent and synthetic benzene derivatives, spices, dyes, plastics, medicine, explosives, rubber, etc

Storage precautions
Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants and edible chemicals, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. The storage area should be equipped with leak emergency treatment equipment and suitable containment materials. 

Operation precautions
Closed operation to enhance ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear a self-priming filter gas mask (half mask), chemical safety protective glasses, protective work clothes, and rubber oil-resistant gloves. Keep away from fire and heat. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevents steam from leaking into the workplace air. Avoid contact with oxidants. When filling, the flow rate should be controlled, and there is a grounding device to prevent static accumulation. When handling, light loading and unloading should be done to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may have harmful residues
