Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
not specified
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Remarks:
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. This is a peer reviewed handbook that has been cited by the US EPA in the Hazardous Substances Databank (HSDB). It is therefore accepted that this data source is reasonably reliable.
Principles of method if other than guideline:
No method specified as data was obtained from handbook.
Key result
Auto-ignition temperature:
420 °C
Atm. press.:
760 mm Hg
Remarks on result:
other: Standard Atomospheric pressure assumed
Conclusions:
The Autoflammability temperature of 2,3-dimethylbutane is 420 °C.
Executive summary:

The Autoflammability temperature of 2,3-dimethylbutane is 420 °C. 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. This is a peer reviewed handbook that has been cited by the US EPA in the Hazardous Substances Databank (HSDB). It is therefore accepted that this data source is reasonably reliable.

Description of key information

The auto-ignition temperature of 2,3 -dimethylbutane is 420 °C.

Supporting data is available for Hydrocarbons, C6, isoalkanes, <5% n-hexane, hexane and Isohexane. This data is used for read across to 2,3 -dimethylbutane.

The autoignition temperature of Hydrocarbons, C6, isoalkanes, <5% n-hexane is >200°C. This value is considered representative for the category by the consotium.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
420 °C
