General description

m-Xylene is an aromatic hydrocarbon primarily used as a solvent in various industrial applications, such as in the production of coatings, paints, rubber products, and adhesives. Additionally, m-xylene serves as a crucial precursor in the production of certain chemicals like phthalic anhydride and isophthalic acid.

Application

m-Xylene can be used as a solvent in the:
  • Formation of vertical nanowires composed of C60 molecules through the solvent vapor annealing (SVA) process.
  • Copper-catalyzed halogen exchange reaction in aryl halides.
