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- other: GLP compliant, guideline study, available as unpublished report, acceptable without restrictions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)
- Remarks on result:
- other: The test item showed no signs of self-heating when held at a temperature of 140 °C for 24.5 hours. When the oven temperature was increased from 140 to 400 °C at a heating rate of 30 °C/hour, significant self-heating occurred at 280 °C
- Conclusions:
- Di-μ-chloro-bis(hapto-1,5-cyclooctadiene)dirhodium(I) showed no signs of self-heating when held at a temperature of 140 °C for 24.5 hours. When the oven temperature was increased from 140 to 400 °C at a heating rate of 30 °C/hour, significant self-heating occurred at 280 °C.
- Executive summary:
This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint.
Di-μ-chloro-bis(hapto-1,5-cyclooctadiene)dirhodium(I)showed no signs of self-heating when held at a temperature of 140°C for 24.5 hours. When the oven temperature was increased from 140 to 400°C at a heating rate of 30 °C/hour, significant self-heating occurred at 280°C.

Description of key information
Di-μ-chloro-bis(hapto-1,5-cyclooctadiene)dirhodium(I)showed no signs of self-heating when held at a temperature of 140 °C for 24.5 hours. When the oven temperature was increased from 140 to 400 °C at a heating rate of 30 °C/hour, significant self-heating occurred at 280 °C.
Key value for chemical safety assessment
Additional information
O'Connor and Woolley (2011) is a GLP compliant study following a modified N4 method and is considered reliable and suitable for use as the key study for this endpoint.
Di-μ-chloro-bis(hapto-1,5-cyclooctadiene)dirhodium(I) showed no signs of self-heating when held at a temperature of 140 °C for 24.5 hours. When the oven temperature was increased from 140 to 400 °C at a heating rate of 30 °C/hour, significant self-heating occurred at 280 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
