Description of key information

A HLC of 2.02E+002 Pa*m3/mole was calculated for diisopropylnaphthalene (DIPN)

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
25 °C

Additional information

Using the method of bond contribution and group contribution, Henry's Law constants of 0.00199 and 0.00194 atm*m³/mol respectively were determined indicating quite rapid volatilization of DIPN from water into air.
