Description

Xylene CAS NO 1330-20-7 is a high-purity aromatic hydrocarbon solvent, primarily a mixture of three isomers (ortho-, meta-, and para-xylene). This versatile compound is valued for its excellent solvency power and relatively high evaporation rate, making it a critical intermediate and processing aid across numerous industries. It is an essential raw material for the production of phthalic anhydride, polyester fibers, and plasticizers, and serves as a key solvent in paints, coatings, and adhesives formulations. Manufacturers and formulators in the chemical synthesis, polymer, and coatings sectors rely on its consistent quality for reliable process performance.

Application

• Chemical Synthesis Intermediate: A primary feedstock for the production of phthalic anhydride, terephthalic acid (PTA), and isophthalic acid.
• Solvent for Paints & Coatings: Used as a powerful solvent in alkyd resins, lacquers, enamels, and rubber cements due to its high solvency and volatility.
• Production of Polymers & Plastics: A key precursor in the manufacture of polyethylene terephthalate (PET) for fibers and bottles, and as a component in plasticizers.
• Adhesives & Sealants: Employed as a solvent and thinner in various adhesive and sealant formulations to adjust viscosity and drying time.
• Cleaning & Degreasing Agent: Effective for cleaning metal surfaces, equipment, and electronic components in industrial settings.
• Printing & Leather Processing: Used in printing inks, rubber processing, and as a solvent in leather tanning and finishing.
• Laboratory & Analytical Reagent: Serves as a solvent for microscopy, histology, and in various analytical procedures.
• Fuel & Gasoline Component: Can be blended into gasoline to increase octane rating, though this is a less common application for high-purity grades.

Quality Control

Our Xylene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent internal specifications, which typically include assessment of isomer composition, purity, density, distillation range, and non-volatile residue. A Certificate of Analysis (COA) detailing these results is provided with every shipment. We can supply grades suitable for industrial, reagent, and specialty applications, with quality assurance protocols aligned with ISO and REACH compliance standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep container tightly sealed when not in use to minimize evaporation and prevent absorption of moisture. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Due to its highly volatile and flammable nature, it must be segregated from strong oxidizing agents and ignition sources.
