Description of key information

Henry's Law of DBTU is < 222.08 Pa.m3.mol-1 at 20°C

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
20 °C

Additional information

The vapour pressure of 1,3 -dibuthylgaunide was evaluated by QSAR .The vapour pressure of DBTU at 20°C is < 0.25 Pa.

The hydrosulbility of DBTU was found equal to 212 mg/l at 20°C.

MW of DBTU is 188.33 g/mol

So as a consequence the Henry's law value is lower to 222.08 Pa.m3.mol-1 at 20°C
