- Type of method:
- effusion method: isothermal thermogravimetry
- Specific details on test material used for the study:
- Physical Description: White powder
Purity/Composition: 99.2%, assumed 100% for testing
Storage Conditions: At room temperature protected from light desiccated - Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The isothermal TGA effusion method was applied for the determination of the vapour pressure of Esacure A 198. The weight losses of the test item had to be determined at temperatures above the melting temperature of the test item. Since weight losses were below that of Benzo(ghi)perylene in the temperature range of 200°C - 230°C, it was safely concluded that vapour pressure is below that of this reference substance.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was:
20°C 25°C
[Pa] [mm Hg] [Pa] [mm Hg]
Test item < 1.3 × 10-8 < 1.0 × 10-10 < 5.5 × 10-8 < 4.1 × 10-10 - Executive summary:
In this guideline study conducted with GLP certification, the test item EC 466-080-8 was determined to have vapour pressures of:
At 20 °C: < 1.3 × 10-8 Pa (< 1.0 × 10-10 mmHg)
At 25 °C: < 5.5 × 10-8Pa (< 4.1 × 10-10mmHg)
