Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
auto-ignition temperature (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: No data on GLP/guideline compliance but 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
Key result
Auto-ignition temperature:
361 °C
Atm. press.:
1 013 hPa
Remarks on result:
other: Pressure not stated, therefore assumed standard
Conclusions:
The autoflammability of cyclopentane was reported as 361ºC.
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 this endpoint. The autoflammability of cyclopentane is therefore 361ºC.

Description of key information

The auto ignition temperature is 360°C for cyclopentane, based on literature values.

Key value for chemical safety assessment

Additional information

The autoflammability temperature is 360°C for cyclopentane based on literature values. This value has been agreed by the consortium to represent the substance. This is supported by a value of 361°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.
