Paraxylene (px CAS:106-42-3) is a colourless flammable liquid, it has a characteristically sweet odour. Its boiling point is 138.4°C. Paraxylene is mainly used as feedstock for the manufacture of purified terephthalic acid (PTA), the principal raw material for polyester.
Physical Properties of p-Xylene
- P-Xylene Density: 0.861 g/cm³
- P-Xylene Melting Point: 13.2°C
- P-Xylene Boiling Point: 138.4°C
P-Xylene is slightly soluble in water but readily soluble in most organic solvents.
Chemical Properties of p-Xylene
P-Xylene is a colorless, transparent liquid with an aromatic odor. Its molecular formula is C₈H₁₀, with two methyl groups positioned at the para-position of the benzene ring. Para-xylene has a boiling point of 138.4°C, a melting point of 13.2°C, and a density of 0.861 g/cm³. It is insoluble in water but miscible with most organic solvents such as ethanol, diethyl ether, and benzene.
Chemically, p-xylene exhibits typical aromatic hydrocarbon properties. It undergoes substitution and oxidation reactions. For instance, in the presence of oxidizing agents, it oxidizes to terephthalic acid; under halogenation agents, it undergoes halogenation to form corresponding halogenated p-xylene derivatives.
p-Xylene Use
- As a solvent for coating, resin, dye, ink and other industries;
- P xylene is used as synthetic monomer in pesticide and other organic chemical industry;
- P xylene can be used as aviation gasoline-additive.
