Physico-chemical data are available for m, p
and o xylene. Data on physical properties were obtained from a number of
secondary sources. The data in these secondary sources are based on a
critical evaluation of peer-reviewed data and the selected values are
considered to be reliable and representative of the property under
investigation. Information on the review process was documented in the
introduction of the source. The use of Klimisch codes (Klimisch et al.
1997) was extended to these secondary sources and a reliability code of
(2) valid with restrictions was assigned when using the authoritative
For the key values, the mean values of
selected physico-chemical properties were used.
The data show that o-, m- and
p-xylenes are liquids, though p-xylene has a melting point of 13 °C.
Therefore the flammability classification for the isomers has been
determined following the criteria for flammable liquids. The flash point
and boiling point of m-xylene are 27°C and 139°C, of p-xylene are 27°C
and 138°C and of o-xylene are 32°C and 145°C respectively. Therefore,
all three of the isomers meet the criteria for flammable liquid category
3 under CLP (flash point ≥ 23°C and ≤ 60°C).
