P-Xylene (Para-Xylene, 1, 4-Dimethylbenzene) Uses
- p-Xylene is oxidized to produce terephthalic acid (PTA). PTA then reacts with ethylene glycol to form polyethylene terephthalate (PET), which is widely used in the synthetic fiber and film industries. Para-xylene (PX) is the main raw material for polyester production. Polyester derived from 1,4-dimethylbenzene (p-xylene) is known for its high strength, light weight, good elasticity, and easy wash-and-dry properties.
- In addition, Para-Xylene CAS 106-42-3 can also be sulfonated to produce surfactants such as ammonium xylene sulfonate and sodium xylene sulfonate.

Storage and Transportation
- P-Xylene (para-xylene, CAS 106-42-3) has relatively low toxicity and is non-corrosive. However, it is highly flammable and volatile, which requires special care during storage and transportation. At normal temperature, p-xylene 1,4-dimethylbenzene may crystallize and solidify, so proper sealed storage and temperature control measures are necessary to ensure safe handling.
- It should be kept away from ignition sources, heat sources, and direct sunlight, and contact with oxidizing agents and strong acids must be strictly avoided.
