Results and discussion
Water solubility
- Key result
- Water solubility:
- > 1 000 g/L
- Conc. based on:
- test mat. (dissolved fraction)
- Temp.:
- 20 °C
- pH:
- 2.6
- Details on results:
- After the stirring period, the test sample was clear and no undissolved test item was observed. It was concluded that the water solubility of 1,4-dioxan-2-one (PDO monomer) at 20°C was > 1 x 10³ g/L. The pH of the aqueous sample was 2.6.
Applicant's summary and conclusion
- Conclusions:
- It was concluded that the water solubility of 1,4-dioxan-2-one (PDO monomer) at 20°C was > 1000 g/L at pH 2.6.
