What is the CAS number of p-xylene?
2025,12,18What is the CAS number of p-xylene?
The CAS number for p-xylene (1,4-dimethylbenzene) is 106-42-3.p-Xylene (CAS No. 106-42-3) is a colorless, clear liquid with a characteristic aromatic odor. It is one of the three xylene isomers and stands out due to the symmetrical positioning of its two methyl groups, which makes it uniquely suited as the primary feedstock for terephthalic acid derivatives.
Main Uses of P-Xylene
Core Use: CAS 106-42-3 P-Xylene is a key raw material for the production of terephthalic acid (PTA) and dimethyl terephthalate (DMT).End Products: PTA and DMT are the two main monomers for the production of polyethylene terephthalate (PET). Therefore, p-xylene is ultimately mainly used in the manufacture of:- PET resin, used to produce: polyester fibers (polyester), polyester films, PET bottles (beverage bottles, etc.).
- Unsaturated polyester resins, coatings, solvents, and plasticizers, etc. (relatively small quantities).
