Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP compliant, guideline study, available as unpublished report, acceptable without restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: N4 (Modified Method) Self Heating Substances
- Deviations:
- yes
- Remarks:
- The test item was only available in very limited amounts and was extremely expensive. Therefore, in order to obtain as much information as possible on the self heating properties of the test item a modified procedure was employed.
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- Carbonyl(pentane-2,4-dionato-O,O’)(triphenylphosphine) rhodium showed no signs of self-ignition or significant heating over the duration of the test.
- Executive summary:
This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint.
Carbonyl(pentane-2,4-dionato-O,O’)(triphenylphosphine) rhodium showed no signs of self-ignition or significant heating over the duration of the test.
Reference
Carbonyl(pentane-2,4-dionato-O,O’)(triphenylphosphine) rhodium showed no signs of self-ignition or significant heating over the duration of the test.
No self heating was observed for the test item when held at temprature of 140 °C for 24 hours. When the teperature increased from 140 to 400 °C at a heating rate of 30 °C/hour, self heating occured at 171 °C. However, the maximum observed temperature rise of the sample above that of the oven was only approx. 23 °C and therefore not considered significant as defined by the method guideline.
Description of key information
Carbonyl(pentane-2,4-dionato-O,O’)(triphenylphosphine) rhodium showed no signs of self-ignition or significant heating over the duration of the test.
Key value for chemical safety assessment
Additional information
O'Connor and Woolley (2011) is a GLP compliant study following a modified N4 guideline and is considered reliable and suitable for use as the key study for this endpoint.
Carbonyl(pentane-2,4-dionato-O,O’)(triphenylphosphine) rhodium showed no signs of self-ignition or significant heating over the duration of the test.
