Preliminary experiment:

The test item showed no thermal effects until a temperature of 300°C.

Main experiment:

In total 9 measurements were performed in the range of 132.1 to 170.9°C:

Test no. Temperature (°C) Vapour pressure (hPa)
1 132.1 22.5
2 141.9 35.2
3 150.4 47.3
4 158.4 63.2
5 164.8 79.2
6 170.9 93.8
7 168.3 87.2
8 164.8 75.1
9 154.5 56.2

The Antoine constants that were determined are:

A = 10.3656

B = -2835.37

C = 273.15

Conclusions:
The test item has a vapour pressure of 0.05 hPa at 20°C, 0.07 hPa at 25°C and 0.39 hPa at 50°C.
Executive summary:

The vapour pressure of the test substance was determined according to OECD 104, dynamic method: vapour-liquid equilibrium. First a preliminary experiment was performed in which the thermal stability of the test substance was assessed by differential scanning calorimetry. The test item showed no endothermal signal up to 300°C. In total 9 measurements were performed in the range of 132.1 and 170.9 °C. The calculated vapour pressures are 0.05 hPa at 20°C, 0.07 hPa at 25°C and 0.39 hPa at 50°C.

Description of key information

For this endpoint one study is available in which the vapour pressure of the test item is assessed according to OCD 104, dynamic method: vapour-liquid equilibrium. The test item was found to have following vapour pressures: 0.05 hPa at 20°C, 0.07 hPa at 25°C and 0.39 hPa at 50°C.

Key value for chemical safety assessment

Vapour pressure:
0.05 hPa
at the temperature of:
20 °C
