Reference 1

Endpoint:

auto-ignition temperature (liquids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2008

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: GLP status not known, information from a published handbook, acceptable with restrictions.

Principles of method if other than guideline:

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Description of key information

The autoflammability temperature of the xylene isomers and ethylbenzene ranges from 432 to 528˚C. The auto flammability of m-xylene is 527˚C, for o-xylene it is 463˚C, for p-xylene it is reported as 528˚C and for ethylbenzene it is reported as 432°C. The mean value of 487.5˚C will be used for the risk assessment.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

487.5 °C

Additional information

The CRC Handbook (2008) is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.
