Ethylbenzene is an important organic chemical raw material, widely used in the production of various chemicals and plastics. This article will detail the properties and uses of ethylbenzene.

1. the nature of ethylbenzene

ethylbenzene is a colorless transparent liquid with aromatic odor. Its molecular formula is C8H10 and its molecular weight is 106.17. The boiling point of ethylbenzene is 136.2 ℃, the melting point is -94.9 ℃, the relative density is 0.866, insoluble in water, but miscible in alcohol, ether and most other organic solvents. Ethylbenzene is flammable, explosive and toxic, so special attention should be paid to safety during production, storage and use.

2. the use of ethylbenzene

1. the production of styrene
the main use of ethylbenzene is the production of styrene, an important organic chemical raw materials. Styrene is widely used in the production of polystyrene resin. This resin has excellent insulation, corrosion resistance, processability and low cost, so it is widely used in the fields of home appliances, construction, packaging, automobiles, etc.

2. Production of ethylbenzene Ethylbenzene
can also be used to produce ethylbenzene, ethylbenzene is an important solvent and fine chemical raw materials, can be used in the production of dyes, pharmaceuticals, pesticides and so on.

3. Production of alkylate
Ethylbenzene can also be used to produce alkylate, which is a high-octane gasoline additive that can improve the combustion performance and anti-knock performance of gasoline.

4. Production of other chemicals
In addition to the above uses, ethylbenzene can also be used to produce some other chemicals, such as ethyl acetate, acetaldehyde, ethylamine, etc.

In conclusion, ethylbenzene, as an important organic chemical raw material, has a wide range of applications in the field of chemical production raw materials.
