Description

Xylene, Ortho-Lean CAS NO 68650-36-2 is a specialized aromatic hydrocarbon mixture characterized by a high concentration of ortho-xylene relative to its meta and para isomers. This specific composition makes it a valuable intermediate and solvent for high-performance industrial applications where reaction selectivity and solvent power are critical. It is essential for manufacturers in the chemical synthesis, polymer, and coatings industries seeking consistent quality and reliable supply for their production processes.

Application

• Primary raw material for the production of phthalic anhydride, a key precursor for plasticizers and unsaturated polyester resins.
• High-performance solvent in paints, coatings, and adhesives formulations requiring strong solvency and controlled evaporation rates.
• Chemical intermediate in the synthesis of specialty chemicals, including certain agrochemicals and pharmaceuticals.
• Component in the formulation of cleaning agents and degreasers for industrial equipment.
• Used in the production of polyester fibers and films.
• As a reaction medium in various organic synthesis processes.
