Description of key information

Vapour pressure [3-(triethoxysilyl)propanethiol]: 1.1 Pa at 25°C (QSAR)
Vapour pressure [3-(trihydroxysilyl)propanethiol]: 1.1E-04 Pa at 25°C (QSAR)

Key value for chemical safety assessment

Vapour pressure:
1.1 Pa
at the temperature of:
25 °C

Additional information

A predicted vapour pressure value of 1.1 Pa at 25°C was determined for the substance using a validated QSAR estimation method. The result is considered reliable and selected as key study. In another secondary source to which no reliability could be assigned, a limit vapour pressure value of <1 hPa was reported for the substance.

The vapour pressure of the silanol hydrolysis product was estimated to be 1.1E-04 Pa at 25°C.

The measured vapour pressure of ethanol is 7910 Pa at 25°C (Daubert, T E and Danner R P (1985))
