Description of key information
Henry's Law of DPG is 4.82e-8 Pa.m3.mol-1 at 20°C
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of 1,3 -diphenylguanidine was evaluated in a study performed in accordance with OECD testing guideline 104 and GLP requirements. The method used is the Knudsen cell effusion method coupled to a microbalance. As the logarithm of the vapour pressure of a pure substance is a linear function of the inverse of the temperature, the vapour pressure is determinate in a limited temperature range (80 -100°C). Three vapour pressure are determinate : at 81°C , P = 6.524Pa, at 90°C P=5.548 Pa and at 100°C P= 5.896 Pa.
The vapour pressure of 1,3 -diphenylguanidine extrapolated at 20°C is 7.4e-11 Pa.
The hydrosulbility of DPG was found equal to 325mg/l at 20°C (i.e. 1.54 mol/m3)
So as a consequence the Henry's law value equals 4.82e-8 Pa.m3.mol-1 at 20°C
