Description of key information

Substance: 6.8 Pa at 25°C
Hydrolysis product ((3-chloropropyl)methylsilanediol): 0.021 Pa at 25°C
Ethanol: 7910 Pa at 25°C

Key value for chemical safety assessment

Additional information

A vapour pressure of 6.8 Pa at 25°C was obtained for the test substance and 0.021 Pa for the hydrolysis product using an appropriate calculation method. The result is considered reliable. The measured vapour pressure of ethanol is 7910 Pa at 25°C (Daubert, T E and Danner R P (1985)).
