Any other information on results incl. tables

The results of the static method for the determination of the vapour pressure of the test substance are given in Table7.

The plot of the log PTof the test substance as function of the reciprocal temperatures shows a coefficient of correlation (r) of > 0.99. Interpolation of the curve to 20°C resulted in a vapour pressure of 84.9´103Pa = 637 mm Hg for the test substance.
