- Executive summary:
The study of vapour pressure using effusion method was performed in accordance with EU Method A.4 (based on the method OECD 104). The vapour pressure of di(tert-butoxy)diacetoxysilane was determined to be 2.88 Pa at 20ºC and 5.34 at 25 ºC.
Reference
Vapour pressure of di(tert-butoxy)diacetoxysilane at 20 ºC and 25 ºC was calculated on the basis of equation log (P) = f (1/t) = a-b/(t+273.15) where, P – vapour pressure in Pa, t – temperature in ºC, obtained for three measurement points: 24.80, 28.50 and 33.20 ºC.
