Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Principles of method if other than guideline:
- The water solubility is determined according to “Flask Method” in “OECD 105 Water
Solubility”. Excessive sample is put in water at 30℃, when saturation is achieved, the mixture
is cooled and kept at 20℃. The mass concentration of the target analyte in the aqueous solution,
can be determined by appropriate method. - GLP compliance:
- no
- Type of method:
- flask method
Test material
- Reference substance name:
- tributyl(ethyl)phosphanium diethyl phosphate
- Cas Number:
- 20445-94-7
- Molecular formula:
- C18H42O4P2
- IUPAC Name:
- tributyl(ethyl)phosphanium diethyl phosphate
- Test material form:
- liquid
Constituent 1
Results and discussion
Water solubility
- Water solubility:
- > 1 000 g/L
- Conc. based on:
- not specified
- Temp.:
- 20 °C
- Remarks on result:
- completely miscible
- Details on results:
- At 20℃, the mixtures of the sample and
water were all homogeneous and transparent,
and no separation into layers, according to the
following ratios:
1:100 (pH = 2.68);
1:10 (pH = 2.13);
1:1 (pH = 3.26);
10:1 (pH = 6.18);
100:1 (pH = 7.61);
Conclusion: The water solubility is >1000
g/L, and the sample is mutually soluble with
water.
Applicant's summary and conclusion
- Conclusions:
- The water solubility is >1000 g/L, and the
sample is mutually soluble with water.（20℃）
