Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Vapour pressure
[triethylsilanol]: 20 Pa at 25°C (QSAR)
Key value for chemical safety assessment
- Vapour pressure:
- 2 700 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of triethylsilane has been predicted based on the known relation between boiling point and vapour pressure. Due to the variation in the boiling point results for triethylsilane, predicted vapour pressure values of 1500 - 2700 Pa at 25°C were obtained for triethylsilane using a validated QSAR estimation method. The result is considered to be reliable. The highest predicted vapour pressure was used for assessment purposes.
In contact with water, triethylsilane hydrolyses slowly to produce triethylsilanol and hydrogen. The vapour pressure of triethylsilanol was determined to be 20 Pa at 25°C using a validated QSAR estimation method.
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.
