- Details on results:
- The TBPEH 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- 2-ethylhexanoat was determined to be 46.3 +/- 10.33 mg/L (95% confidence interval) at 20 ° C ± 1 °C using the shake-flask method.
- Executive summary:
The solubility of tert.-Butylperoxy- 2-ethylhexanoat in water at 20 ± 1 °C was determined using the shake-flash method . The water solubility of tert.-Butylperoxy- 2-ethylhexanoat was determined to be 46.3 ± 2.40 mg/L (95% confidence interval) at 20 °C ± 1 °C using the shake-flask method for the performance of the main test.
