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.
