Conclusions:

The relative density of diisobutyl phosphate was found to be 1.047.

Executive summary:

The relative density of diisobutyl phosphate was determined by an oscillating densitometer in accordance to OECD Guideline 109.

The liquid sample was introduced into an oscillating tube of the densitometer instrument. The change in the oscillating frequency due to the change in mass of the tube was used to determine the density of the sample. The instrument was calibrated with water and checked with a standard oil. the density of water at 4 °C is used as reference. The relative desity of diisobutyl phosphate was found to be 1.047.

Description of key information

The relative density of diisobutyl phosphate was measured with an oscillating densiometer and determined to be 1.047.

Key value for chemical safety assessment
