- Executive summary:
The vapour pressure of the test material was investigated in accordance with the standardised guidelines OECD 104 and EU Method A.4, under GLP conditions.
The vapour pressure was determined using the isothermal thermogravimetric effusion method. According to EU Safety Data Sheet the melting point for the test material is >300 °C. The evaluation of the vapour pressure could be performed only with the reproducible weight loss values above ≥ 1 μg/min and in this case was performed with the results above 220 °C and thus below the melting point.
A value of the vapour pressure of the test material was determined using the data obtained between 190 and 250 °C.
Under the conditions of this study, the vapour pressure of the test material was calculated (mean of three determinations) to: 3.16 × 10 ^-5 Pa at 20 °C.
Reference
- According to EU Safety Data Sheet the melting point for the test material is >300 °C. The evaluation of the vapour pressure could be performed only with the reproducible weight loss values above ≥ 1 μg/min and in this case was performed with the results above 220 °C and thus below the melting point.
- The results of the isothermal TGA analysis are given in Table 1.

Estimation of VT and PT:
log VT at 20 °C: -8.1840246
log PT at 20 °C: -4.5007613
PT at 20 °C: 0.0000316
PT (Pa) at 20 °C: 3.16E-05
- The coefficient of correlation (R^2) was 0.9854. The resulting equation was:
log PT = 4.7300 + 1.1279 · log VT
Inserting the equation for log VT above, the following equation for the temperature dependence of the vapour pressure of the test material is obtained:
log PT = C+D · (a · (1000/T) +b) = C+(D · b)+(D · a · 1000 )/T
(where: a = -4.2103, b = 6.1856, C = 4.7300 and D = 1.1279)
With this equation, a following vapour pressure results were obtained: 3.16 × 10^-5 Pa at 20 °C.

Additional information
The vapour pressure of the test material was investigated in accordance with the standardised guidelines OECD 104 and EU Method A.4, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The vapour pressure was determined using the isothermal thermogravimetric effusion method. According to EU Safety Data Sheet the melting point for the test material is >300 °C. The evaluation of the vapour pressure could be performed only with the reproducible weight loss values above ≥ 1 μg/min and in this case was performed with the results above 220 °C and thus below the melting point.
