Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Up to 2008
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Source is a published handbook, no data on GLP/guideline compliance/method. Acceptable with restriction as handbook is peer reviewed and considered a reliable source.
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.
GLP compliance:
not specified
Remarks:
not reported
Type of method:
other: Not reported
Key result
Flash point:
-51 °C
Atm. press.:
1 013 hPa
Remarks on result:
other: Pressure not stated, therefore assumed standard
Conclusions:
The flash point for 2-methylbutane was reported as -51°C.
Executive summary:

There is no available information on the methods used to determine the value for this endpoint. However, this information is taken from the CRC Handbook which is considered to be a reliable peer reviewed handbook and suitable for use as the key study for flash point endpoint. Therefore the flashpoint for 2-methylbutane was reported as -51°C.

Description of key information

The flash point is <0°C for 2-methylbutane based on DIN 51755 methodology. This is supported by a value of -51°C from the CRC Handbook (Lide 2008).

Key value for chemical safety assessment

Additional information

The flash point is <0°C for 2-methylbutane based on DIN 51755 methodology. This is supported by a value of -51°C from the CRC Handbook (Lide 2008). There is no information available on the methods used to determine the value for this endpoint. However, the CRC Handbook is considered to be a reliable, peer-reviewed handbook and suitable for use as a study for this endpoint.
