Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 [ tri(isopropoxy)(vinyl)silane]: 64 Pa at 25°C (QSAR)

Vapour pressure [vinylsilanetriol]: 0.017 Pa at 25°C (QSAR)

Vapour pressure [isopropanol]: 6053 at 25°C

Key value for chemical safety assessment

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

Additional information

A predicted vapour pressure value of 64 Pa at 25°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable.

In contact with water, the submission substance reacts rapidly to form vinylsilanetriol and isopropanol.

The silanol hydrolysis product, vinylsilanetriol, has a predicted vapour pressure of 0.017 Pa at 25°C using a validated QSAR method.

Isopropanol has a reported vapour pressure of 6053 Pa at 25°C (Daubert and Danner 1989).
