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 90°C, 100°C, 110°C and 120°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 <=8.2E-5
Pa and <=1.8E-4 Pa, resp.
