Melting Point of Para-Xylene (p-Xylene)
The melting point of p-xylene is 13–14°C.
It solidifies easily at relatively low temperatures, forming white crystal-like solids if stored in cooler climates or winter seasons.
What Is p-Xylene (PX)?
Para Xylene (P-xylene) is a colorless, transparent liquid with a distinctive aromatic odor. Chemically, it belongs to the aromatic hydrocarbon family, with a molecular structure comprising eight carbon atoms and ten hydrogen atoms. At standard temperature and pressure, p-xylene is highly volatile and insoluble in water, yet it is mutually miscible with numerous organic solvents.

p-xylene (PX) uses
p-Xylene is one of the most important petrochemical feedstocks.
-
PTA(purified terephthalic acid) Production (Main Use)
Over 99% of p-xylene is used to produce PTA (Purified Terephthalic Acid)-the core raw material for:
- PET bottles
- Polyester fibers
- Polyester film
- Packaging materials
-
PET (polyethylene terephthalate) Resin
Used in beverage bottles, food packaging, and medical containers.
Only a very small portion is applied in other fields such as the pharmaceutical intermediate dimethyl terephthalate (DMT) and coatings.
