Description

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.[1]
• Copper-catalyzed halogen exchange reaction in aryl halides.[2]
