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.
