Benzene: one of the basic raw materials in petrochemical industry

Benzene is a colorless, aromatic and oily transparent liquid, which is one of the basic raw materials of petrochemical industry. However, it is also a highly flammable, highly toxic and carcinogenic substance. In this paper, the properties, uses and hazards of benzene will be discussed in depth to help readers better understand this organic compound.

Flammable, highly toxic and carcinogenic.

Benzene is a highly flammable, toxic and carcinogenic substance. Long-term exposure to benzene and its products will cause serious harm to human body, so we need to realize the harmfulness of benzene and try to avoid contact.

Natural characteristics

Benzene has the properties of saturated hydrocarbon substitution reaction and unsaturated hydrocarbon addition reaction, which is insoluble in water and soluble in organic solvents. Its melting point is 5.5℃ and boiling point is 80.65438 0℃. If cooled with water, it can condense into colorless crystals.

Widely used

Benzene has a wide range of uses, which can be used as a solvent for fat, resin and iodine, and can also be used to determine the refractive index of minerals, organic synthesis, optical pure solvent, high pressure liquid chromatography solvent and so on. In addition, benzene is also an important raw material for synthesizing dyes, medicines, pesticides, photographic films and petrochemical products.

It is recommended to open more windows for ventilation.

The release period of benzene is not fixed. For the sake of our health, it is suggested to open more windows for ventilation to let benzene volatilize.

Protect the environment and ensure health.

In order to protect our health, we need to realize the harm of benzene. In life and work, we should try to avoid long-term exposure to benzene and its products. At the same time, improving the technical level of petrochemical industry and reducing the production and emission of benzene are also one of the keys to protect people's health and national sustainable development.
