EC number: 218-320-6
CAS number: 2116-84-9
is a liquid at
ambient temperature and pressure, with a measured melting point of <-20°C
and a predicted boiling point of 280°C. It has a predicted density of
0.95 g/cm3 at 20°C and a predicted vapour pressure of 0.09 Pa
The substance is not classified
for flammability in accordance with Regulation (EC) No. 1272/2008 on the
basis of a measured flash point of 112.0 ± 1.0°C and
a predicted boiling point of 280°C. It has a measured auto-ignition
temperature of 430°C at 98.5 - 98.8 kPa,
and is not explosive and not oxidising on the basis of structural
In contact with water, the
substance reacts slowly with an estimated half-life of >200 hours at pH
7, >1.9 hours at pH 4 and >2.0 hours at pH 9 and 20-25°C.
The stated half-life is for removal of parent. Complete reaction
to the ultimate end products will take longer. The equation for the
reaction is stated below:
3H2O ¿ 3(CH3)3SiOH + C6H5Si(OH)3
a predicted log Kow of 9.0 at 20°C and a measured water
solubility of 0.0066 mg/l at 23°C. The substance is not surface active
based on structural examination.
