Description of key information

The solubility of buta-1,3-diene in water is 0.735g/l at 20˚C. As buta-1,3-diene and buta-1,2-diene are similar substances it is considered suitable for read-across.

Key value for chemical safety assessment

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

Additional information

The study by McAuliffe (1966) predates the implementation of GLP and standard guidelines. However, the method is described in detail and is considered appropriate for determining the solubility of a gaseous substance.
