Description: Dark brown paste
Storage conditions: Room temperature in the dark - Boiling pt.:
- > 633 K
- Atm. press.:
- 102 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 365 K
- Conclusions:
- The test item decomposed from approximately 365 K at 102 kPa, prior to any boiling.
- Executive summary:
In an EU Method A.2 study, conducted according to GLP, the test item decomposed from approximately 365 K at 102 kPa, prior to any boiling. Given the chemical structure(s) of the test item, the fact that the substance is non-volatile, and as such the vapour pressure study yielded a limit value, the boiling temperature is estimated to be greater than 360 deg C (> 633 K) (SafePharm Laboratories Limited, 1998).
Reference
As the test item decomposed prior to boiling, no value for the boiling temperature could be determined.
It is not possible to calculate a definitive boiling temperature from the data obtained in the vapour pressure study on the test item because only an estimate of the maximum vapour pressure was obtained. This is due to the test item being non-volatile and, as such, the vapour pressure study yielded a limit value. Based on these results and the chemical structure, the boiling temperature is estimated to be greater than 360 deg C (> 633 K).
A determination at reduced pressure was not performed as experience has shown that no further useful information is obtained for test materials of this nature which decompose prior to boiling at atmospheric pressure.
