- Details on results:
- The tert-Butylperoxy-3,5,5-trimethylhexanoat concentrations were calculated with the help of the calibration equations.
The repeatability of the determination was <15% and thus within the range required by the guidelines. - Conclusions:
- In conclusion the water solubility of tert-Butylperoxy-3,5,5-trimethylhexanoat was determined to be 14.2 ± 2.40 mg/L (95% confidence interval) at 20 °C ± 1 °C using the shake-flask method for the performance of the main test.
- Executive summary:
The solubility of tert-Butylperoxy-3,5,5-trimethylhexanoat is in water at 20 ± 1 °C was determined using the shake-flash method. The water solubility of tert-butyl 3,5,5-trimethylperoxyhexanoate was determined to be 14.2 ± 2.40 mg/L (95% confidence interval) at 20 ° C ± 1 °C using the shake-flask method for the performance of the main test.
