Results and discussion
Water solubility
- Water solubility:
- 217 g/L
- Temp.:
- 30 °C
- pH:
- 4.5
- Details on results:
- The high percentage of inorganic salts present in the test substance (see project OC 018-93) possibly influences the solubility of Reaktiv-Gelb F-66923 in water. Therefore it was decided to perform the experiments with amounts lower than required in the guideline. (Requirement of the guideline: The study has to be performed with amounts 5 times higher than the water solubility determined by preliminary experiments.)
Within the error of the method, these results are independent of stirring time at 30 °C. An average can be calculated from these data.
Average: 402.34 g/l
Standard deviation: 8.12 g/
(rel. standard deviation: 2.0 %)
