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).
