Paraxylene (PX, CAS 106-42-3) is an important aromatic hydrocarbon used mainly as a chemical intermediate in the petrochemical industry. Purity is a key quality parameter, as it has a direct impact on downstream processing efficiency, final product quality, and overall process stability, particularly in polyester production.
What is the purity of paraxylene?(CAS:106-42-3)
Paraxylene is available commercially in many grades of purity.
Common Purity Grades
- Industrial Grade: ≥ 99.5%
- Polymer / PTA Grade: ≥ 99.7% (sometimes up to 99.8%)
For most large-scale applications, especially purified terephthalic acid (PTA) production, paraxylene with a purity of 99.7% or higher is preferred to ensure stable oxidation reactions and minimize catalyst poisoning.
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.
