Styrene is an organic compound. It is a monomer of polystyrene. polystyrene is not a natural compound. Polymer made from styrene is known as polystyrene. It is a synthetic compound. In this compound a benzene ring is present. Therefore, it is also known as an aromatic compound. In this article, we have covered all the important points and concepts about styrenes like styrene formula, its uses, synthesis of styrene, styrene structure, and its properties. 


Styrene Formula

The structural styrene formula is C6H5CH=CH2. The styrene chemical formula is C8H8. The number written in the subscript of C represents the number of carbon atoms and the number written in the subscript of H represents the number of hydrogen atoms. C6H5 represents the benzyl ring and the CH=CH2 represents the two carbon alkene chains. The IUPAC name of the styrene is Ethenylbenzene.


Styrene Structure

In the styrene structure, one benzene ring is attached to the vinyl group by the covalent bonding. Four pi bonds are present in the styrene structure. These pi bonds are alternately present in the styrene. Due to such arrangement resonance phenomena occur in the styrene structure. Other than these pi bonds eight sigma bonds are also present in the styrene structure. These sigma bonds present in the styrene are formed by the head-on overlapping s orbitals. The pi bonds are formed by the lateral overlapping of the p orbitals. 


Styrene Properties

  • Styrene is a colourless liquid.

  • The molecular weight of the styrene is 104.15 g/mol.

  • The styrene density is 0.909 g/cm³ at normal room temperature.

  • The odour of styrene is sweet in nature.

  • The solubility of styrene is 0.24 g/lt.

  • Styrene is flammable in nature.

Styrene Uses

  • Polymeric Solid form of styrene is used for packaging purposes.

  • Styrene is used in making rigid food containers.

  • Polymeric styrene is used in making medical devices and optical devices.

  • Electronics devices, children’s toys, kitchen appliances, household items, and many other products are made with the help of styrene.

  • Polystyrene foam is a lightweight material. Therefore, can be used in protective packaging for food services purposes.

  • Polystyrene is used in making building components like insulation material and more.

  • Styrene is used in making Composite products, these products are known as fiber-reinforced polymer composites (FRP). These components are used in making automobile components.

  • Styrene polymeric form is used in making corrosion-resistant pipes and tanks.

  • Styrene is used in bathroom fixtures and sporting goods.

  • Polystyrene films are used in laminating, and printing applications.

Styrene Based Products

  • Refrigerator liners, medical equipment, car parts, small household appliances, toys, and luggage are all made of the plastic Acrylonitrile Butadiene Styrene (ABS).

  • Food containers, tableware, bathroom fixtures, and optical fibers are all made of Styrene Acrylonitrile (SAN) plastic.

  • SBR (Styrene Butadiene Rubber) is a synthetic rubber that replaces natural rubbers in a range of applications, including vehicle tyres (leading to improved fuel efficiency), conveyor belts, gaskets, and seals.

  • Styrene Butadiene Latex (SBL) is a form of latex that is used to attach carpet fibers to a backing material in many paper coatings and more than 90% of broadloom carpeting made in the United States.

Environment Aspects of Styrene

Styrene is commonly used because it allows a wide range of goods to have a wide range of cost-effective advantages that customers enjoy. Styrene-based materials are used to produce bicycle helmets, military armour, and wind turbines. Styrene-based goods help to minimize greenhouse gas emissions by offering energy-efficient insulation in buildings and construction, as well as improved fuel efficiency by strengthening and reducing the weight of vehicle components. They also allow for the production of high-performance and cost-effective recreational goods like boats and other watercraft, as well as a reduction in reliance on expensive natural resources like tropical hardwoods for boats and marble and granite for homes and buildings.
