p-Xylene is an aromatic hydrocarbon, based on benzene with two methyl substituents. The 'p' stands for para, identifying the location of the methyl groups as across from one another.
It is an isomer of xylene. Other isomers include o-xylene and m-xylene. P-xylene is used on a large scale for the manufacture of terephthalic acid for polyester. Its polymer is known as parylene.
Global demand for para-xylene is around 32 million tonnes in 2006, essentially all of this manufacture going into polyester production for fibres and films (eg PET soft drinks bottles).
