What is p-xylene (1,4-Dimethylbenzene CAS 106-42-3 )?
P-xylene(1,4-Dimethylbenzene CAS:106-42-3), a colorless transparent liquid with an aromatic odor, possesses distinct physical properties. Its density is 0.861, melting point is 13.2°C, boiling point reaches 138.5°C, and flash point is 25°C. This compound is readily miscible with organic solvents such as ethanol, diethyl ether, and acetone.
Production of p-xylene (1,4-Dimethylbenzene CAS:106-42-3)
The production of p-xylene (1,4-Dimethylbenzene CAS:106-42-3) mainly relies on petroleum refining and chemical processing. Crude oil undergoes distillation and cracking processes to produce intermediates containing various aromatic hydrocarbons. These intermediates are then processed through catalytic reforming or steam cracking to produce mixed xylenes.
P-xylene (1,4-Dimethylbenzene CAS:106-42-3) Uses
P-xylene (1,4-Dimethylbenzene) is a basic chemical raw material with a wide range of downstream applications.
- In the textile industry, p-xylene (1,4-Dimethylbenzene) is the main raw material for the production of polyester fiber. Polyester fiber is widely used in clothing, home textiles, and industrial textiles due to its high strength, good abrasion resistance, and ease of washing.
- In the packaging industry, 1,4-Dimethylbenzene is used to produce polyethylene terephthalate (PET), a common plastic material used in the manufacture of beverage bottles, food containers, etc.
- P-xylene is also used as a solvent, acting as a dissolver and diluent in paints, inks, and adhesives.
- In the pharmaceutical and pesticide industries, P-xylene can also be used as an intermediate in the synthesis of certain drugs and agrochemicals.
