Ethylbenzene, identified by its CAS number 100-41-4, is a fundamental aromatic hydrocarbon with significant industrial importance. This colorless liquid, characterized by its flammability and a distinct odor similar to gasoline, serves as a critical raw material in the petrochemical industry. Its primary and most substantial application is as the direct precursor to styrene monomer, a key component in the production of polystyrene, a versatile plastic used extensively in packaging, construction, electronics, and consumer goods.

The large-scale industrial production of ethylbenzene is typically achieved through the alkylation of benzene with ethylene, a process that has been refined over decades to maximize efficiency and product purity. This makes ethylbenzene a crucial ethylbenzene chemical intermediate, forming the first step in the value chain for many plastic products. The process of production of styrene from ethylbenzene via catalytic dehydrogenation is a mature and vital industrial operation, underpinning the global polymer market. The consistent availability and quality of ethylbenzene are therefore paramount for downstream manufacturers.

In addition to its role as a styrene precursor, ethylbenzene also exhibits valuable properties as an industrial solvent. Its solvency power makes it useful in the formulation of paints, coatings, inks, and adhesives, illustrating its diverse ethylbenzene uses as solvent. Furthermore, ethylbenzene is found in certain fuel blends, acting as an anti-knock agent to improve octane ratings and enhance engine performance, thereby also serving as an ethylbenzene fuel additive. The inherent flammability of ethylbenzene necessitates stringent safety measures, including proper storage, handling, and ventilation protocols, to mitigate risks.
