- Executive summary:
This study following EU Method A.2 (Boiling temperature) is considered suitable for use as key study for this endpoint. The boiling point /boiling range of 1,10-Decanediamine, 4-methylbenzenesulfonate (1:2) was determined by differential thermal analysis.
1,10-Decanediamine, 4-methylbenzenesulfonate (1:2) has no boiling point at atmospheric conditions.
Boiling accompanied by decomposition of the substance starts at approximately 347 °C.
Reference
Differential thermal analysis (DTA):
1,10-Decanediamine, 4-methylbenzenesulfonate (1:2) was heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere. Endothermal or exothermal effects were measured and recorded.
The DTA measurement showed a first endothermal effect at approximately 138 °C, which is interpreted to be the presumed melting point of the substance.
A second endothermal effect was observed at approximately 347 °C. After the measurement, the test item was discoloured to black. Therefore this second effect is interpreted to be the initial boiling point accompanied by the decomposition of the substance.
Description of key information
1,10-Decanediamine, 4-methylbenzenesulfonate (1:2) has no boiling point at atmospheric pressure. Boiling accompanied by decomposition of the substance starts at approximately 347 °C.
Key value for chemical safety assessment
Additional information
A study (Boiling point Currenta 2018) following EU Method A.2 (Boiling temperature) was performed to determine the boiling point of 1,10-Decanediamine, 4-methylbenzenesulfonate (1:2)
It was concluded that the test item has no boiling point at atmospheric conditions as boiling accompanied by the decomposition of the substance starts at approximately 347 °C.
