Product Name:o-Xylene
English Name:o-Xylene
CAS No.:95-47-6
Aliases:1,2-dimethylbenzene, o-xylol, ortho-xylene
Molecular Formula:C8H10
Physical Properties:Colorless transparent liquid with a toluene-like odor. Insoluble in water but miscible with ethanol, ether, chloroform, and most organic solvents. Density 0.88 g/cm³ (water=1), vapor density 3.66 (air=1). Melting point -25.5°C, boiling point 144.4°C, flash point 32°C (closed cup), autoignition temperature 463°C, explosion limit 1%–7% (by volume).
Uses:o-Xylene is an important organic chemical feedstock, mainly used to produce phthalic anhydride, which serves as a precursor for plasticizers and alkyd resins. It is also widely used as a solvent in the synthesis of dyes, pesticides, pharmaceuticals, and vitamins. Additionally, it can be used as an aviation gasoline additive.
