what is paraxylene px?
Paraxylene (px) is an aromatic hydrocarbon with the chemical formula C8H10. A colourless flammable liquid, it has a characteristically sweet odour. Paraxylene is mainly used as feedstock for the manufacture of purified terephthalic acid (PTA), the principal raw material for polyester.
What is the use of paraxylene (CAS:106-42-3)?
The primary use of paraxylene (CAS:106-42-3) is as a raw material for producing purified terephthalic acid (PTA). PTA serves as a key intermediate in manufacturing polyethylene terephthalate (PET), which is widely used in products such as fibers, films, and plastic bottles.
Paraxylene is also used to produce other chemical products, such as benzoic acid and p-toluenaldehyde. These compounds have significant applications in pharmaceuticals, pesticides, coatings, and other fields. For instance, benzoic acid serves as a raw material for manufacturing preservatives, widely used in the food and pharmaceutical industries. P-Toluenaldehyde, meanwhile, functions as an intermediate in the production of pesticides and dyes.
What are the physical properties of paraxylene (CAS:106-42-3)?
The physical properties of paraxylene (CAS:106-42-3) include its density, boiling point, melting point, and solubility. PX has a relatively low density of approximately 0.861 g/cm³, enabling it to float on water. Its melting point is 13.2°C, indicating that paraxylene exists as a liquid at room temperature but may solidify in cold environments.
With a boiling point of 138.4°C, PX evaporates at elevated temperatures, a beneficial characteristic for distillation separation techniques. Paraxylene is insoluble in water but readily soluble in most organic solvents.
