Products Description
Para-xylene, also known as P-Xylene; 1,4-dimethyl-benzene, commonly referred to as PX, is one of the three isomers of xylene. It is a vital chemical intermediate in the global petrochemical industry. At room temperature, it is a colorless, transparent liquid with an aromatic odor. Paraxylene chemical is insoluble in water but miscible in most organic solvents, such as ethanol, ether, chloroform, acetone, and benzene.

Industrial Production of p-Xylene
p-Xylene is mainly produced through petroleum refining and catalytic reforming of naphtha fractions. It is typically obtained from mixed xylene streams and separated using advanced industrial separation processes.
Common separation technologies include:
- Adsorbtive separation (Parex process)
- Crystallization separation
- Distillation and extraction methods
These processes allow the selective recovery of high-purity p-xylene suitable for downstream chemical production.
Applications：
1. PTA Production:
Over 85% to 90% of paraxylene is utilized in the production of Purified Terephthalic Acid (PTA), a key raw material for polyester.
2. Polyester and PET:
The PTA produced from paraxylene is used to manufacture polyester fibers, PET resins, polyester films, and engineering plastics.
3. Solvent Applications:
Used in the fields of coatings, paints, adhesives, and chemical processing.
4. Chemical Intermediates:
Used in the production of plasticizers, resin intermediates, synthetic materials, and industrial additives.
Health Hazards
Para-xylene can enter the human body through inhalation, skin absorption, and oral intake. It has a stimulating effect on the eyes and upper respiratory tract, and high concentrations can have an anesthetic effect on the central nervous system.
Environmental Hazards
It has a certain degree of volatility, and its vapor may cause pollution to the atmospheric environment. At the same time, if it enters water bodies, it may cause harm to aquatic organisms.
Protective Measures
In the process of production, storage, and use of P-Xylene (PX), effective protective measures should be taken, such as wearing protective glasses, gloves, masks, etc., ensuring good ventilation in the workplace, and setting up combustible gas alarms.

Frequently Asked Questions
Q: What is p-xylene used for?
p-Xylene is mainly used in the production of purified terephthalic acid (PTA), which is a key raw material for polyester fibers, PET bottles, polyester films, and engineering plastics. More than 85% of global p-xylene consumption is directed to the polyester industry.
Q: Is p-xylene flammable?
Yes. p-Xylene is classified as a Class 3 flammable liquid. It should be stored away from ignition sources and handled in well-ventilated areas using appropriate personal protective equipment (PPE).
Q: What purity of p-xylene is commonly supplied for industrial use?
Industrial-grade p-xylene is typically supplied at a purity of 99.0% or higher. For PTA production and other petrochemical applications, higher purity specifications may be required to ensure process efficiency and product quality.
Q: What documents are typically provided?
Standard export and industrial supply documentation may include a Certificate of Analysis (COA), Safety Data Sheet (SDS), Technical Data Sheet (TDS), packing list, commercial invoice, and certificate of origin.
Q: What testing parameters are included in a p-xylene COA?
Typical quality control parameters include purity, density, color (APHA), sulfur content, water content, non-aromatic impurities, and distillation range. Specific testing standards may vary according to customer specifications and industry requirements.
Q: Is p-xylene regulated for transportation?
Yes. p-Xylene is regulated as a hazardous flammable liquid under international transportation regulations. Proper labeling, packaging, and documentation are required for shipment.
