Xylène — Wikipédia

Le préfixe o- (xylène), p- ou m- indique à quels atomes de carbone du noyau aromatique sont fixés les groupements méthyle. En numérotant les atomes de carbone à partir d''un atome lié à un groupement méthyle, le composé est du o-xylène (1,2-diméthylbenzène) si l''atome de carbone adjacent, numéroté 2, est également lié à un groupement méthyle.

Published March 1998. A significant amount of new xylene isomer capacity is being built worldwide, especially for p-xylene, which has experienced sustained demand growth of 7-8% per year. While p-xylene production economics were extremely attractive in 1994-1995, there is now concern about surplus capacity and reduced profitability.

Xylene - Wikipedia

The physical properties of the isomers of xylene differ slightly. The melting point ranges from −47.87 °C (−54.17 °F) ( m -xylene) to 13.26 °C (55.87 °F) ( p -xylene)—as usual, the para isomer''s melting point is much higher because it packs more readily in the crystal structure. The boiling point for each isomer is around 140 °C (284 °F).
