Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Referenceopen allclose all
The vapour pressure of the substance is reported to be 0.523 hPa at 25°C.
The vapour pressure of the substance is reported to be 0.1 hPa at 20 °C and 10 hPa at 90 °C.
Description of key information
A vapour pressure value of 0,523 hPa (52,3 Pa) at 25°C is retained for Triethylphosphat. (handbooks)
Low volatility (based on volatility bands criteria for occupational exposure (Chesar / ECETOC TRA), 0,01 - 500 Pa).
Key value for chemical safety assessment
- Vapour pressure:
- 0.523 hPa
- at the temperature of:
- 25 °C
Additional information
Two handbooks, considered as reliable sources, report vapour pressure values for the substance, and are therefore presented in a Weight-of-Evidence approach:
The vapour pressure of the substance is reported to be 0.523 hPa at 25°C in (Yaws et al, 1994) and 0.1 hPa at 20°C and 10 hPa at 90°C in (Verschueren, 1996)
The higher, i.e. worst-case value is retained as key data.
As supporting data, (Daubert & Danner, 1989) reports a consistent value of 0.39 mmHg (= 52 Pa) at 25°C .
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
