Conclusions:
The determined final result for water solubility of tert-Butylperoxy isopropyl carbonates was an average result for the time points 24, 48 and 72 hours and was calculated to be 2.2 g/L. The pH value of the samples, taken at the different time points, was measured with pH indicator strips to be 7. The temperature at which the test was conducted varied from 19.9 – 20.1 °C.
Executive summary:

The water solubility of tert-Butylperoxy isopropyl carbonatewas determined in accordance with OECD guideline 105 at a temperature of 20.0 ± 0.5°C.The dataon water solubility represent the saturation mass concentration of the test substance in water.

 

The determined final result for water solubility oftert-Butylperoxy isopropyl carbonatewas 2.2 g/L.
