CAS 36265-41-5 Chemical Name: Styrene vs. Vinylbenzene

Guangxing Product Page

Styrene and Vinylbenzene are two commonly used chemicals in various industries. While they are similar in many ways, there are also key differences between the two. .

**Structure**.

Styrene, also known as vinylbenzene, has a chemical formula of C8H8 and a molecular weight of 104.15 g/mol. It consists of a benzene ring with an attached ethenyl group. On the other hand, Vinylbenzene has a chemical formula of C8H8 and a molecular weight of 104.15 g/mol. It also has a benzene ring with an attached vinyl group. .

**Physical Properties**.

Styrene is a colorless to yellowish oily liquid with a sweet smell, while Vinylbenzene is a colorless liquid with a strong, unpleasant odor. Both chemicals have a density of around 0.9 g/cm3 and a melting point of around -30°C. However, their boiling points differ, with Styrene boiling at 145°C and Vinylbenzene at 191°C.

**Chemical Properties**.

Both Styrene and Vinylbenzene are highly reactive chemicals. Styrene polymerizes easily in the presence of heat, light, or initiators, and is commonly used in the production of polystyrene plastics. On the other hand, Vinylbenzene is often used as a chemical intermediate in the production of various polymers and resins.

**Applications**.

Styrene is widely used in the production of plastics, rubber, insulation, and fiberglass. It is also used in the manufacturing of resins, pipes, and packaging materials. On the other hand, Vinylbenzene is mainly used as a monomer in the production of polymers such as polystyrene, acrylics, and synthetic rubbers.

In conclusion, while Styrene and Vinylbenzene share similarities in their chemical structures and uses, they also have distinct differences in terms of physical and chemical properties. Understanding these differences is essential in selecting the appropriate chemical for specific industrial applications.
