Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (substance): 44.3 Pa at 20°C 
Vapour pressure (silanol hydrolysis product): 0.00005 Pa at 20°C

Key value for chemical safety assessment

Vapour pressure:: 44.3 Pa
at the temperature of:: 20 °C

Additional information

A vapour pressure of 44.3 Pa at 20°C was extrapolated using a temperature-vapour pressure correlation developed from data measured in the range -40 to 415°C (DIPPR 2001). Several secondary sources, to which a reliability could not be assigned, report vapour pressure values of 181.3 to 2670 Pa over a range of temperatures from 40 to 152.5°C. The vapour pressure of the silanol hydrolysis product has been predicted to be 0.00005 Pa at 20 °C, using a validated QSAR prediction method. The result is considered to be reliable.

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).
