Henry's Law of DPG is 4.82e-8 Pa.m3.mol-1 at 20°C
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
