2,2-dimethylbutane

Auto flammability

Link to relevant study record(s)

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 and 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:

425 °C

Atm. press.:

760 mm Hg

Remarks on result:

other: Standard Atmospheric Pressure Assumed

Conclusions:

The auto-flammability temperature of 2,2-dimethylbutane is reported to be 425 °C.

Executive summary:

The auto-flammability temperature of 2,2-dimethylbutane is reported to be 425 °C. No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

Description of key information

The auto-ignition temperature of 2,2 -dimethylbutane is 425 °C.

The autoignition temperature is > 200°C for the supporting read-across substances: hydrocarbons, C6, isoalkanes, <5% n-hexane; and iso-hexane. This range has been agreed by the consortium to represent the substance.
