key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment

The water saturation already occurs after one hour: the value after two hours is within the experimental error. The average value of 230.5 mg/l represents the water solubilty of the test item, according to the experimental method used.

The final analysis after degassing the solution, shows that the test item is no more present.

The limit value of the analysis method is < 5ppm (weight-weight concentration).

Conclusions:
The water solubility of the test item at 20°C is 230.5 mg/l
Executive summary:

Due to the test item nature (gas), the water solubility have been determined according to a specific method. The methods described in the recognised international guidelines are not adapted for gases.

A gas stream of test item has been bubbled into a flask containing distilled water. Then samples are taken and analysed by gas chromatography.

The water solubility is express as the mean of the data obtained after 1 and 2 h of incubation at 20°C.

The water solubility of the test item is 230.5 mg/l.

Description of key information

Due to the test item nature (gas), the water solubility have been determined according to a specific method. Indeed, the methods described in the recognised international guidelines are not adapted for gas.

A gas stream of test item has been bubbled into a flask containing distilled water.Then samples are taken and analysed by gas chromatography.

The water solubility is express as the mean of the data obtained after 1 and 2 h of incubation at 20°C.

Key value for chemical safety assessment

Water solubility:
230.5 mg/L
at the temperature of:
20 °C
