Pyrolysis Gasoline

Product Summary

Pyrolysis gasoline is a mixture of C6 to C8 hydrocarbons that is produced as a by-product of naphtha cracking. It contains a large number of aromatic hydrocarbons and serves as a raw material used to extract benzene, toluene, and xylene.

Characteristics

Pyrolysis gasoline (mixture)

  • Flash point: ≤-20°C    Density: 0.85-0.86 g/cm3 (15ºC)

Benzene

  • Boiling point: 80.1ºC
  • Benzene is an aromatic hydrocarbon with the simplest structure.
  • It consists of six carbon atoms arranged in a planar hexagonal pattern.

Toluene

  • It has a structure in which one of the hydrogen atoms in the benzene ring is replaced with a methyl group.
  • It is highly insoluble in water and miscible in alcohol and oil.
  • It is widely used as a solvent but is volatile and flammable at room temperature.
  • It has anesthetic effects at high concentrations and is very toxic.

Xylene

  • Xylene has three different isomers: 1,2-dimethylbenzene (ortho-xylene), 1,3-dimethylbenzene (meta-xylene), and 1,4-dimethylbenzene (para-xylene).
  • These isomers are flammable and burn with soot. They are highly insoluble in polar solvents and soluble in nonpolar solvents.

Styrene

  • Boiling point: 145-146ºC

Properties

Light yellow liquid with an oily smell
