What is paraxylene (PX) in chemicals?
Paraxylene (PX CAS:106-42-3) is a crucial aromatic hydrocarbon widely used in the petrochemical industry, primarily as a building block for producing purified terephthalic acid (PTA) and dimethyl terephthalate (DMT)-key intermediates in the manufacture of polyethylene terephthalate (PET).
What are the properties of paraxylene (PX)?
Paraxylene is a colorless, transparent liquid with an aromatic odor and distinct physical characteristics. It has a density of 0.861, a melting point of 13.2°C, a boiling point of 138.5°C, and a flash point of 25°C. This compound is readily miscible with organic solvents such as ethanol, diethyl ether, and acetone.
What is paraxylene (PX) used for?
Paraxylene (PX) is primarily used in the production of polyester fibers (such as polyester) and plastic containers (such as beverage bottles), accounting for over 95% of its total consumption. Below are specific application classifications:
Polyester Fiber (Polyester) Manufacturing: Used in apparel, home textiles (e.g., curtains, bed sheets), and industrial materials (e.g., tire cord fabric), accounting for over 90% of paraxylene consumption.
Production of plastic products:
- Polyester containers like beverage bottles and food packaging boxes.
- Films (e.g., cling wrap, packaging film).
Other industrial applications
Solvent: Used in paint, rubber processing, and aviation fuel additives.
Chemical feedstock:
- Production of dyes, pesticides, and pharmaceutical intermediates.
- Synthetic fragrances and inks.
Laboratory applications: Serves as a standard substance for chromatographic analysis.
