The saturation equilibrium diisobutyl ketone - water was established by ultraviolet analysis and the Fisher method.

The solubility of water in DiBK is 0.4 wt.% at 23 °C and the solubility of DiBK in water is 0.043 wt.% at 25 °C.

Conclusions:
Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
The water solubility of diisobutyl ketone is 0.043 wt.% (430 mg/L) at 25 °C.
Executive summary:

The water solubility of diisobutyl ketone is 0.043 wt.% (430 mg/L) at 25 °C.

Description of key information

 The solubility of 2,6-dimethylheptan-4-one (diisobutyl ketone) in water is found to be 430 mg/L at 25 °C and 500 - 600 mg/L at 20 °C 

Key value for chemical safety assessment

Water solubility:
430 mg/L
at the temperature of:
25 °C

Additional information

The solubility of 2,6-dimethylheptan-4-one (diisobutyl ketone) in water is found to be 430 mg/L at 25 °C and 500 - 600 mg/L at 20 °C. Thus 2,6-dimethylheptan-4-one is moderately soluble (100-1000 mg/L) in water.
