Key result
Water solubility:
29 g/L
Conc. based on:
test mat. (total fraction)
Loading of aqueous phase:
50 g/L
Incubation duration:
72 h
Temp.:
20 °C
pH:
11.6
Remarks on result:
other: Mean value of three measurements. Temperature was indicated as "room temperature" and is assumed to be 20 °C.
Details on results:
Results: Preliminary test, water solubility: 1-10 g/l
Sample 1, 24 h: water solubility = 28.44 g/l, pH = 11.60
Sample 2, 48 h: water solubility = 29.46 g/l, pH = 11.60
Sample 3, 72 h: water solubility = 29.20 g/l, pH = 11.70
Values 1-3 are used for the calculation of the average of values.
Conclusions:
The water solubility of calcium dibenzoate is determined using the flask method to 29.0 g/L at room temperature with a pH of 11.6.
