Description of key information
The water solubility of the test item 1,8-naphthylendiamine in demineralized water was determined with the shake flask method at 20 °C according to OECD 105 and OPPTS 830.7840. The concentration of 1,8-naphthylenediamine in aqueous test solutions was determined by HPLC analysis with UV detection. Water solubility of 1,8-naphthylendiamine was determined to be 0.772 g/L (at 20 °C). The relative standard deviation between the single determinations is < 15 %. The validity criteria have therefore been met.
Key value for chemical safety assessment
- Water solubility:
- 0.772 g/L
- at the temperature of:
- 20 °C
Additional information
In a preliminary test, the water solubility of the test item was found to be > 10^-2 g/L (approximately 640 mg/L). Therefore, the shake flask method was chosen for the determination of the water solubility. For the main test, a quantity of the test item necessary for saturation is dissolved in demineralized water. The vessels are stoppered and stirred on a magnetic stirrer for 24 h, 48 h and 72 h at 30 °C in a temperature controlled water bath. Following this procedure, the temperature is reduced to 20 °C and is kept in the temperature controlled water bath for another 24 h. After phase separation by filtration with a disposable syringe filter and/or centrifugation (20 minutes, 9000 rpm, 20 °C), the concentration of 1,8-naphthylenediamine in aqueous test solutions was determined by HPLC-analysis with UV-detection.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
