Applicant's summary and conclusion
- Executive summary:
The vapour pressure was determined at different temperatures by the gas saturation method. The value for 25°C was extrapolated by use of the Antoine equation. A nitrogen gas stream flows through about 0,5 g of the test item coated on glass beads at different constant temperatures. With a nitrogen stream slowly enough, it is saturated with the test item according to it's pure-component vapour pressure: the partial pressure becomes identical to the pure-component vapour pressure. The nitrogen carrier gas stream saturated with the test item is passed into a cold cap (U-tube) leading to condensation of all vapourized test item. The condensed test item is dissolved with a solvent and the condensed amount of the test item is determined by means of a gas chromatography. With the ratio of the mass of the evaporated test item to the volume of the saturated nitrogen at a defined temperature, th partial pressure of the test item can be calculated

With the optimized Antoine equation the vapour pressure for T = 25°C is calculated: p (hPa) = 1.46 E -05.
