What is p-xylene (PX CAS:106-42-3)?
P-xylene (PX CAS:106-42-3) is an organic compound with the chemical formula C8H10, and is one of the important aromatic hydrocarbons. At room temperature, PX is a colorless, transparent liquid with an aromatic odor. It is insoluble in water but miscible with most organic solvents such as ethanol, ether, and chloroform.
What is p-xylene (PX CAS:106-42-3) used for PET resin?
P-xylene (PX CAS:106-42-3) is an important aromatic hydrocarbon used in the polyester industry. It is a core raw material in the manufacture of polyethylene terephthalate (PET) resin, which is widely applied in packaging materials, textile fibers, and engineering plastics.
Role of P-xylene (PX CAS:106-42-3) in PET Resin Production
P-xylene (PX CAS:106-42-3) is not used to produce PET directly. In industrial practice, it is first converted into purified terephthalic acid (PTA) or dimethyl terephthalate (DMT). These intermediates then react with ethylene glycol through a polycondensation process to form PET resin.
