experimental study
Adequacy of study:
key study
Study period:
13 March - 15 May, 2007
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Study has been performed according to OECD and/or EU guidelines and according to GLP principles.
Qualifier:
according to
Guideline:
OECD Guideline 105 (Water Solubility)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.6 (Water Solubility)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
flask method
Key result
Water solubility:
7.31 g/L
Temp.:
19.7 °C
pH:
ca. 6.9
Details on results:
The maximum difference (MD) of the mean concentrations determined in the 24, 48 and 72 hour test samples was < 15%. According to the guidelines, the water solubility of the test substance is given as the mean value of the mean analysed concentrations.
No test substance was detected in the pretreated samples from the blank water mixture.
Conclusions:
The substance is soluble (1000-10000 mg/L).
The flask method was chosen for the determination of the water solubility of Ditetrahydrofurylpropane. The water solubility of the test substance at 19.7 +/- 0.6°C was 7.31 g/l. The pH of the aqueous samples after 72 hours stirring was 6.9.
