Vapour pressure (3-chloropropyl)methylsilanediol) 0.021 Pa at 25°C (QSAR)

Key value for chemical safety assessment

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

Additional information

There are no reliable measured data for (3-chloropropyl)dimethoxymethylsilane. A vapour pressure of 52 Pa at 25°C was determined for the substance using an appropriate QSAR predictive method. The result is considered to be reliable and selected as key study. A vapour pressure of 1300 Pa at 20°C was also reported for the substance in a secondary source, full details are not available and the reliability is unassignable.

The vapour pressure of the hydrolysis product was determined to be 0.021 Pa using an appropriate QSAR estimation method.

A measured vapour pressure of 12,790 Pa at 20°C is available for methanol (OECD, 2004)
