- Executive summary:
The test item shows a boiling and/or thermal decomposition earliest at ca. 449 °C (at 994 mbar) according to the definition in the OECD guideline 103.
Reference
The boiling temperature of the test item was determined in accordance with the test method OECD Guideline Test 103 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 27th July 1995, Boiling Point” (similar to the test method A.2. "Boiling temperature" as described in the Official Journal of the European Communities L383A)
The practical test performance was based on the in-house test procedure VTA(S)31X93002.02: "Boiling temperature determination(Tb) of solid and liquid substances by means of DSC".
To determine the boiling behaviour (three independent single measurements), the test item was measured by DSC between 5 °C and 550 °C with a heating rate of 10 K/min. For the measurement a partially capsulated crucible, typical for boiling point measurements, was used. The test item shows a boiling and/or thermal decomposition earliest at ca. 449 °C (at 994 mbar) according to the definition in the OECD guideline 103.
450 °C (from first measurement)
449 °C (from second measurement)
449 °C (from third measurement)
From 449 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components.
The DSC measurements were confirmed by means of TGA measurements under the same measuring conditions.
Description of key information
The test item shows a boiling and/or thermal decomposition earliest at ca. 449 °C (at 994 mbar) according to the definition in the OECD guideline 103.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 449 °C
