p xylene flash point (CAS 106-42-3)
The flash point of p-xylene is 25–28°C (closed cup).
This means it is classified as a flammable liquid, requiring strict control of storage temperature, ventilation, and ignition sources in industrial environments.
What Is p-Xylene (PX)?
P-xylene (para xylene), often called PX, is an organic compound, the chemical formula is C8H10, is one of the important aromatic compounds, at room temperature is a colorless transparent liquid with an aromatic flavor, insoluble in water, miscible in ethanol, ethyl ether, chloroform and other most organic solvents, mainly used as a raw material for the production of polyester fibers and resins, coatings, dyes, and pesticides, but also used as a standard for chromatographic analysis. It is mainly used as raw material for the production of polyester fiber and resin, paint, dyestuff and pesticide, and also used as standard for chromatographic analysis and solvent.
