[Chemistry Class Notes] on Uses of Benzene Pdf for Exam

Benzene is a clear, colourless, and highly flammable organic chemical compound. It is an aromatic compound with a sweet-smelling odour. A molecule of benzene comprises six carbon atoms joined in a ring-shaped with a hydrogen atom connected to each carbon atom. Therefore, the chemical formula of benzene is C6H6. As the composition of benzene only contains carbon and hydrogen atoms, it is classified as a hydrocarbon. Benzene is also known to be the parent compound of many other aromatic compounds.  Benzene is found abundantly in nature. It is one of the main constituents of crude oil. It is found mainly as a component in gas emissions of volcanic eruptions and forest fires. Benzene is a toxic gas, and exposure to it can cause leukaemia.

Benzene Uses

In the above paragraphs, we read about benzene and its chemical properties. Now, here we will read what is benzene used for. Benzene is an essential component in the gas emission of partially burned natural products and is useful in many fields. It forms a significant part of gasoline and is extensively used as an industrial chemical. Benzene uses in everyday life includes manufacturing plastics, synthetic fibres, rubber, paints and dyes, detergents, and many more. Some of the vital benzene applications and uses are mentioned below:

• Benzene is used as a solvent

• Used in the production of rubber

• In the manufacturing of paints and printing

• Used as a fuel

• Used in the production of chemicals and plastic

• Used in Auto Repairs

Benzene, used as a Solvent

Benzene is extensively used as an industrial solvent. It is also used for commercial and research purposes. It is used as a solvent in many production companies. It is used in many production stages. It is also used as an absorbing and binding agent.

Used in the Production of Rubber

Benzene is commonly used in the manufacturing of tires and rubbers. Manufacturers use products containing benzene as a solvent in many manufacturing processes. For instance, the adhesive used to glue soles to shoes contains a high amount of benzene.

In Paints and Printing Industries

Did you know most of the products used in printing industries contain benzene? Benzene is primarily found in products that are used to clean the printing equipment. The use of benzene in the cleaning products makes the printing equipment long-lasting and properly functional. Many other printing products such as inks and dyes are manufactured using benzene. Most paints, such as spray paints, base and top coat paints, lacquers, stains and sealers contain a significant part of benzene to keep them in liquid form. These products are used by professional painters in painting homes, buildings and even automobile parts.

Benzene as a Fuel

Benzene is an essential product used in the production of gasoline. Benzene forms a large part of crude oil, and most of the products manufactured by oil refineries contain benzene in them. Benzene is also used in the production of lubricants which are used for the maintenance of heavy machinery in the production industries. Due to its abundant availability in nature, benzene is also used as an industrial fuel. It is mainly used in the production of asphalt, which is used as an adhesive in roofing and paving companies. 

In the Production of Chemicals and Plastic

Benzene acts as a significant ingredient in the production of plastic and other chemicals. It is used in the manufacturing of resins, adhesives and other synthetic fibres such as nylon, styrene and styrofoam. Some other chemicals that are produced using benzene are detergents, dyes, etc. Even some agricultural products such as insecticides, pesticides and herbicides are also prepared using benzene.

In Auto Repairs

The solvents that are used in auto repair facilities and automobile industries contain benzene. The solvents containing benzene are used for cleaning the hydraulic systems, fuel system compartments and braking system. The use of benzene helps dissolve the grease that builds upon the automobile parts, and it also does not harm the metal.

Health Hazards of Benzene

The products that contain benzene have certain side effects upon exposure. Continuous exposure to benzene can result in headaches, instability, unconsciousness and irritation. Depending on the exposure, the effects can be acute and major. High exposure to benzene can even lead to death. 

Fun Facts About Benzene

Here are some amusing facts about benzene:

• Benzene evaporates very quickly, and as it is heavier than air, it mostly settles on the lower levels.

• Benzene is the most used chemical in the United States. 

• Benzene slightly dissolves water, and most of it floats above the water. 

• Benzene is used widely in pesticides and insecticides.

Relevance of studying About Benzene in Chemistry

Benzene has a lot of uses on an industrial scale as well as in retail. It is a colourless and highly flammable liquid that’s strongly smelling. It is omnipresent and that too is in abundance.  It is used to manufacture plastics, synthetic fibres, paints, detergents, drugs and a lot of other stuff. 

Understanding the chemical composition and the uses of benzene will help students in Chemistry especially when they move on to Organic Chemistry. Students who wish to pursue a career in Pharmacology, Medicine, Research, Engineering or the like will need to know about benzene in detail. A lot of questions that come for the competitive exams will also come from here.  The relevance of studying benzene cannot be understated.

How to Revise Before a Test on Benzene?

Students can check out Uses of Benzene – Definition, In Production, Uses, Facts and FAQs on and then understand the chapter in-depth.

This page has a lot of relevant details on the same and has covered almost every aspect of benzene as a chemical.  They can read from here and then make notes on the same. They must follow the order in which the topics and sub-topics are mentioned on this page. They must pay attention to the examples that have been used so that they can relate to them.
