- Executive summary:
The vapour pressure of the test substance was measured in accordance with OECD Guideline 104. The vapour pressure at 20 ± 1ºC was 0.149 ± 0.002 Pa (N = 3, CV = 1.0%) using the spinning rotor gauge method.
Reference
Vapour pressure at 20 ± 1ºC was 0.149 ± 0.002 Pa (N = 3, CV = 1.0%).
Description of key information
OECD Guideline 104
Key value for chemical safety assessment
- Vapour pressure:
- 0.149 Pa
- at the temperature of:
- 20 °C
Additional information
Due to the rapid hydrolysis of terephthaloyl dichloride, data for the primary degradation product, terephthalic acid, is provided. Vapour pressure of terephthalic acid is 0.0012 Pa at 25ºC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
