Vapor Pressure Estimations (25 deg C):  (Using BP: 450.00 deg C (user entered, literature data))  (Using MP: 167.00 deg C (user entered, literature data))    

VP: 1.17E-009 mm Hg (Antoine Method)

VP: 1.69E-008 mm Hg (Modified Grain Method)

VP: 4.06E-008 mm Hg (Mackay Method)

Selected VP: 1.69E-008 mm Hg = 2.25E-6 Pa(Modified Grain Method)

Conclusions:
The vapour pressure of the substance was calculated to be 0.00000225 Pa at 25°C.
