Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
auto-ignition temperature (gases)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP non compliant, guideline not known, information from 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.

Conclusions:
The autoflammability of Buta-1,3-diene is 420˚C
Executive summary:

The autoflammability of Buta-1,3 -diene is 420˚C. No information on the test method used is available in the handbook. 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. In addition, this value is consistent with the value cited in the EU RAR (2002) for Buta-1,3-diene.

Conclusions:
The autoflammability of Prop-1-ene, 2-methyl- is 465˚C
Executive summary:

The autoflammability of Prop-1 -ene, 2 -methyl- is 465˚C. No information on the test method used is available in the handbook. 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.

Endpoint:
auto-ignition temperature (gases)
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP status not known, guideline not known, information from a reliable peer-reviewed source and considered adequate for assessment.
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 International Chemical Safety Cards (ICSC) are produced by the WHOs International Programme on Chemical Safety (IPCS). The introduction to the ICSC states that they report “information collected, verified and peer reviewed by internationally recognized scientists”. Therefore, the values presented are acceptable as they are from a reliable secondary source of phys chem. data.

Conclusions:
The self-ignition temperature of 1,3-Butadiene is 414°C.
Executive summary:

The self-ignition temperature of 1,3-Butadiene is 414°C. No information on the test methods used is available in the ICSC. However, this information is taken from a peer reviewed source and so can be considered reliable and suitable for use as the supporting study for this endpoint.

Description of key information

The autoflammability data were not available for any of the streams within this Category. However, data were read across from the main hydrocarbon C4 substances in this Category. The representative constituents of the category studied and used as supporting read-across are But-1-ene (CAS 106-98-9), 2-Butene (CAS 107-01-7, cis and trans isomers of 2-Butene), Buta-1,3-diene (CAS 106 -99 -0) and Prop-1-ene, 2-methyl- (CAS 115-11-7).


 


No information on the test methods used is available in the handbook. 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.


 


The autoflammability of the representative constituents of this Category range from 324 to 465°C.
