15 000 Pa
at the temperature of:
25 °C

Additional information

A vapour pressure of 1.5E+04 Pa at 25°C was obtained for the test substance using an appropriate calculation method.

Vapour pressures of 6.5 Pa and 0.05 Pa at 25°C were obtained for the hydrolysis products, methylsilanediol and methysilanetriol respectively, using an appropriate calculation method.

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