- Key result
- Melting / freezing pt.:
- 118.56 °C
- Decomposition:
- yes
- Decomp. temp.:
- 118.56 °C
- Sublimation:
- no
- Conclusions:
- The melting point under decomposition referring to the pre-test was determined under these circumstances as the endothermic event with 118.56 ± 0.35 °C (391.71 ± 0.35 K).
- Executive summary:
The determination of the melting point of the test item was performed via DSC (differential scanning calorimetry) according to OECD TG 102 and EC 440/2008 Method A.1. In all runs one event was detected. The event is endothermic and is stated as the melting point. The melting point under decomposition referring to the pre-test was determined under these circumstances as the endothermic event with 118.56 ± 0.35 °C (391.71 ± 0.35 K). The test item decomposes right after melting, thus, the decomposition temperature is stated as 118.56 °C.
Reference
Pre-Test
The capillary tube containing the test item was set into the block at 18.8 °C. The block was heated until melting started. At 125 °C the test item began to melt and at 135 °C it was completely melted to a clear colourless liquid and began to boil. After cooling down no test item was in the capillary. The test item melted under decomposition.
Security Pre-test for the DSC instrument
The lid of the crucible was bloated and at the outside two black points were visible after reaching a temperature of 420 °C. After further heating to 600 °C and cooling down the crucible was the same as after reaching 420 °C. The weight was recorded with 34.06 mg after reaching 420 °C and 33.68 mg after reaching 600 °C.
Description of key information
The melting point of the test item was determined to be 118.56 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 118.56 °C
Additional information
The determination of the melting point of the test item was performed via DSC (differential scanning calorimetry) according to OECD TG 102 and EC 440/2008 Method A.1 (reference 4.2-1). In all runs one event was detected. The event is endothermic and is stated as the melting point. The melting point under decomposition referring to the pre-test was determined under these circumstances as the endothermic event with 118.56 ± 0.35 °C (391.71 ± 0.35 K). The test item decomposes right after melting, thus, the decomposition temperature is stated as 118.56 °C.
