Due to the high molecular weight of the test item (minimum Mw = 1634.87 g/mol), an experimental determination of the vapor pressure cannot be carried out. Therefore the extrapolation of the normal boiling temperature is not possible.

The lower range of the molecular weight of the test item is in the order of 1600 g/mol. On page 4 typical values for the vapor pressures of n-hectane (C1QOH202, Mw == 1400) are given. At a temperature of 300°C, the vapor pressure of n-hectane can be calculated as 10-3 mbar (= 0.1 Pa) using the vapor pressure equation. At 200°C the vapor pressure is in the order of 10-8 mbar (= 10-6 Pa) and therefore not be determined experimentally.

As the molecular weight of the test item is even higher, vapor pressure would have to be carried out at temperatures above 300°C. As it can be assumed that high molecular organic substances, as in the case of the test item, are thermally unstable at these temperatures, an experimental determination of the vapor pressure of the test item is not feasible.
