The equation of the pressure-temperature curve: log P[Pa] = -3777*1/T[K] + 12.86 (r = 0.995, n = 8).
The weight losses of the test substance were obtained with a temperature program which started above the melting temperature of the test substance. Due to the low melting point of the test substance this cannot be avoided. As a result, the vapour pressure of the test substance (which was, according to the method, extrapolated to 20 °C and 25 °C) could be slightly overestimated.

Key value for chemical safety assessment
- Vapour pressure:
- 1.6 Pa
- at the temperature of:
- 25 °C
