EC number: 220-449-8
CAS number: 2768-02-7
The distribution in a sewage
treatment plant (STP) has been estimated using the SimpleTreat model
(implemented in EUSES 2.1.2), see table below. Due to the very rapid
hydrolysis of trimethoxy(vinyl)silane (CAS 2768-02-7; EC No. 220-449-8),
the distribution calculation is done for the hydrolysis products,
vinylsilanetriol (CAS 143-48-6) and methanol (CAS 67-56-1; EC No. 200-659-6).
Fraction of emission directed to water by STP
Fraction of emission directed to air by STP
Fraction of emission directed to sludge by STP
Fraction of the emission degraded in STP
hydrolyses very rapidly to form vinylsilanetriol and methanol. Methanol
is readily biodegradable. Vinylsilanetriol
is not expected to undergo any significant biodegradation and is
predicted to have low Henry’s Law constant and low log Kow/log
modelling for STP indicates that water is the main compartment to which
it is expected to partition in a sewage treatment plant. Water is also
likely to be the main compartment to which vinylsilanetriol will
partition in the wider environment.
