Water solubility:
< 10.1 µg/L
Conc. based on:
test mat.
Temp.:
20 °C
pH:
6.3
Remarks on result:
other: Water solubility ranges from < 4.3 μg/L (Peak 1) to < 5.8 μg/L (Peak 2), (as a formal value the sum of the components < 10.1 μg/L can be given)
Details on results:
Water solubility ranges from < 4.3 μg/L (Peak 1) to < 5.8 μg/L (Peak 2) (as a formal value the sum of the components < 10.1 μg/L can be given).

Determination of the water solubility at flow rates of 6.25 mL/h and 12.5 mL/h yielded values below the lowest calibration level (Peak 1 < 4.3 μg/L and Peak 2 < 5.8 μg/L).

with n.d. for not detectable; the other signals were detectable, but all concentrations are below the lowest calibration level (Peak 1 < 1.7 μg/10 mL and Peak 2 < 2.3μg/10 mL). It was decided to give these values, because the chromatograrns clearly show the presence of the test item.

The water solubility of Octadecanoic Acid, reaction products with triethylenetetramine ranges from < 4.3 μg/L (Peak 1) to < 5.8 μg/L (Peak 2), as a formal value the sum of the components < 10.1 μg/L can be given.

Conclusions:
The water solubility of Octadecanoic acid, reaction products with triethylenetetramine at 20 °C is reported to range from < 4.3 μg/L (Peak 1) to < 5.8 μg/L (Peak 2), as a formal value the sum of the components < 10.1 μg/L can be given.
Executive summary:

Water solubility of Octadecanoic acid, reaction products with triethylenetetramine was determined according to OECD Guideline 105 (27 July 1995) using the column elution method.

Determination of the water solubility at flow rates of 6.25 mL/h and 12.5 mL/h yielded values below the lowest calibration level (Peak 1 < 4.3 μg/L and Peak 2 < 5.8 μg/L).

Water solubility of Octadecanoic Acid, reaction products with triethylenetetramine, at 20 °C and a pH of 6, ranges from < 4.3 μg/L (Peak 1) to < 5.8 μg/L (Peak 2), as a formal value the sum of the components < 10.1 μg/L can be given.
