Description of key information
The water solubility of N-(n-octyl)-2-pyrrolidinone is 1250 mg/L at 20 degrees centigrade. It is therefore not completey miscible with water.
Key value for chemical safety assessment
- Water solubility:
- 1 250 mg/L
- at the temperature of:
- 20 °C
Additional information
Two studies are available from the migrated NONS file provided by ECHA. One finds the solubility in water of N-(n-octyl)-2-pyrrolidinone to be 1360 mg/L at 20 degrees centigrade, and the other finds the solubility in water to be 1140 mg/L at 20 degrees centigrade and a pH of 6.9. The mean value is 1250 mg/L, and it is concluded that that this value shall be used as the water solubility for N-(n-octyl)-2-pyrrolidinone, and it is not completely miscible with water.
