The SRC AOPWIN program(v1.92) has been used to obtain values of
the rate constantkOH for reaction of
trimethoxyphenylsilaneand phenylsilanetriolwith hydroxyl radicals. This
prediction method has not been validated to assess applicability to
silanes and silanols; therefore, there is uncertainty associated with
the calculated values obtained.
The overall half-life in air under default conditions of hydroxyl
radical concentration was calculated using the following expressions:
kdegair(d-1) = kOH(cm3/molecule.sec)
x OH Concair(molecules/cm3) x 24 x 3600
DT50(d) = ln 2/ kdegair(d-1)
kdegair= total rate constant for degradation in
kOH= rate constant for reaction with hydroxyl
OH Concair= concentration of hydroxyl radicals in air
=5 x 105OH molecules/ cm3
The results are given in Table 4.1.2.
