Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item at 20°C (293K) was 2.4E-3 Pa and 1.8E-5 mm Hg.
The vapour pressure of the test item at 25°C (298K) was 3.9E-3 Pa and 2.9E-5 mm Hg. - Executive summary:
The vapour pressure of the test item (PT) was determined by the isothermal thermogravimetric effusion method. The method is validated in the range 10E-8 - 10E3 Pa using a set of five reference substances with known vapour pressures. The validity of the method was verified maximum one month before this study using hexachlorobenzene as reference control substance. Since the logarithm of the evaporation rate at 20°C (log vT, 20) deviated < 10% from the average value obtained during the validation test, it was possible to apply the constants obtained with the validation test for the determination of the vapour pressure of the test item. An amount of 15.8 or 19.6 mg of the test item was applied to the surface of a roughened glass plate as a homogeneous layer. The weight loss of the test item was measured continuously as a function of time. The weight loss of the test item was measured continuously as a function of time at defined isothermal temperatures. The evaporation rate of the test item (vT) was calculated from the weight loss of the compound. The PT values at the defined isothermal temperatures were determined using the vapour pressure equation with the constants c and d specific for the experimental arrangement. Linear regression analysis of the log PT values and 1/T was performed using a least squares method. The PT values of the test item at 20°C and 25°C were determined using the vapour pressure regression curve. The vapour pressure of the test item at 20°C (293K) was 2.4E-3 Pa and 1.8E-5 mm Hg. The vapour pressure of the test item at 25°C (298K) was: 3.9E-3 Pa and 2.9E-5 mm Hg.
