Xylene CAS#1330-20-7
Xylene CAS#1330-20-7 High Solubility: Xylene demonstrates excellent solubility in most non-polar organic solvents and is readily soluble in ethanol, ether, chloroform, and acetone, while being practically insoluble in water, which supports its wide usage as an industrial solvent and synthetic raw material.
Stable pH: Pure xylene is a neutral organic solvent with no acidic or alkaline properties. Its aqueous extract maintains a stable neutral pH under normal heating and storage conditions, showing stable chemical inertness in conventional application environments.
Versatile Uses: It serves as a high-efficiency industrial solvent for coatings, paints, inks, and adhesives, an important intermediate in organic synthesis, and a common cleaning agent in precision instrument processing. It is also widely used in petrochemical refining and polymer material manufacturing industries.
Liquid Form & Volatile Nature: This material is provided as a colorless transparent liquid with characteristic aromatic odor and volatile tendencies, making it suitable for industrial scenarios requiring fast volatilization and uniform dissolution performance.
Xylene, characterized by the molecular formula C₈H₁₀, presents as a colorless transparent flammable liquid with a special aromatic odor. It exhibits high solubility in ethanol, diethyl ether, chloroform, and most hydrocarbon solvents, while displaying almost no solubility in water at 25°C. The compound features stable chemical properties at room temperature, does not react with water or weak acid and weak base solutions, and maintains stable neutral properties. The substance possesses flammable and irritant characteristics and is utilized as a core solvent in paint and coating industries, a synthetic intermediate for plastic, rubber and fiber materials, and a diluent for various industrial chemical products.
