The vapour pressure of the substance was determined using the isothermal thermogravimetric effusion method in a GLP study based on EC A.4, OECD 104 and OPPTS 830.7950. Validation of the method was performed using a set of five reference substances.
The vapour pressure regression curve (log PT as function of 1/T; with T in K) of the substance was constructed from weight losses measured at 100°C, 110°C, 120°C and 130°C.
The vapour pressure of the substance at 20°C and 25°C was calculated from the vapour pressure curve.
Since the weight losses of the test item were obtained with a temperature program of above the melting temperature of the test item, the vapour pressure of the test item could be slightly overestimated. The vapour pressure of the substance at 20°C and 25°C was therefore reported as ≤ 9.3E-5 Pa and ≤ 1.9E-4 Pa, resp.
