Key value for chemical safety assessment
Additional information
Phototransformation in air is not expected to be a significant removal process for reaction mass containing six benzylated amine silanes or its hydrolysis products. The substance is not expected to evaporate into the atmosphere from the water surface due to the low vapour pressure of the substance and its hydrolysis products.
The AOPWIN model (v 1.92) was used to estimate the rate constant kOH for reaction of the hydrolysis products of reaction mass containing six benzylated amine silanes with hydroxyl radicals. However, since this prediction method has not been validated to assess applicability to silanes and silanols, results should be treated with caution.
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)
Where:
kdegair= total rate constant for degradation in air
kOH= rate constant for reaction with hydroxyl radicals
OH Concair= concentration of hydroxyl radicals in air =5 x 105OH molecules/ cm3
DT50= half-life
The results are presented in the following table.
