Description of key information

Henry's Law of N Nitrosodiphenylamine is <4.84e6 Pa.m3.mol-1 at 20°C

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
484 200
at the temperature of:
20 °C

Additional information

The vapour pressure of N-Nitrosdiphenylamine evaluated by QSAR at 20°C is < 0.09 Pa.

The hydrosulbility of N-Nitrosdiphenylaminew

as found equal to 35 mg/l at 20°C.

MW of N-Nitrosodiphenylamine is 188.33 g/mol

So as a consequence the Henry's law value is lower to 4.84200e6 Pa.m3.mol-1 at 20°C
