Xylene

Xylene is a colorless, flammable, slightly greasy liquid with the molecular formula (CH₃)₂C₆H₄. It is derived from benzene by replacing two hydrogen atoms with methyl groups (-CH₃) attached to the benzene ring. It is Produced by the methylation of toluene and benzene. Various Types of Xylene is:

  • Ortho-Xylene (o-Xylene): This isomer has the methyl groups positioned next to each other on the benzene ring.
  • Meta-Xylene (m-Xylene): The methyl groups are attached to the benzene ring with one carbon atom separating them.
  • Para-Xylene (p-Xylene): The methyl groups are located opposite each other on the benzene ring.

 

Physical properties

  • It’s a colorless liquid at room temperature,
  • Possesses a sweet, aromatic odor, though less intense compared to benzene.
  • Xylene is also flammable and insoluble in water, but can mix well with many organic solvents.

 

Application

  • Used as a Solvent in Paints, varnishes , thinners, Adhesives, Printing inks, Rubber processing Industry.
  • Xylene serves as a chemical intermediate in the production of various chemicals, including polyester fibers, dyes, pesticides, and pharmaceuticals.
