- test mat.
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not tested
- Conclusions:
- A saturated solution (solution with residue) of the test item Reactive Red 230 could not be prepared because the test mixture at a concentration of 1000 g/L is a high viscous solution.
A higher concentration with an excess of the test item could not be stirred.
Due to this fact, the water solubility is reported from the preliminary screening.
The water solubility of Reactive Red 230 is > 1000 g/L. - Executive summary:
In a first preliminary test 10 mL of demineralized water was submitted into an Erlenmeyer flask. Then approx. 2 g of the test item was stirred until a clear solution was received.
This process was repeated (stepwise addition of approx. 1 g) until the added amount get a concentration of 1000 g/L.
In a second preliminary test, the test item was weighed (5, 7, 8, 9, 10 g each) into separate Erlenmeyer flasks (A through E).
Then 10 mL demineralized water was added to each flask and the mixtures were stirred for 24 hours.
The behavior of the solutions as a function of time has been observed.
After 24 hours the limit case concentration (1000 g/L) of the test item Reactive Red 230 was a high viscous clear solution.
