Description of key information

Vapour pressure [triethoxy(3-thiocyanatopropyl)silane]: 0.011 Pa at 25°C (QSAR)
Vapour pressure [(3-thiocyanatopropyl)silanetriol]: 2.0E-06 Pa at 25°C (QSAR)

Key value for chemical safety assessment

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

Additional information

A predicted vapour pressure of 0.011 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 a secondary source to which no reliability could be assigned, a limit vapour pressure of <1 hPa at 20°C was reported for the substance.

A predicted vapour pressure of 2.0E-06 Pa at 25°C was determined for the silanol hydrolysis product.

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