The vapour pressure of the test item was was calculated by interpolation and extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50°C. The measured vapour pressure

values together with the measured temperatures are listed in the table in the next section "overall remarks".

Conclusions:
The vapour pressure of the test item Reaction mass of N-butylphthalimide and N-sec-butylphthalimide and N-propylphthalimide was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. The vapour pressure of the test item was 0.03 hPa at 20°C, 0.04 hPa at 25°C and 0.20 hPa at 50°C.
Executive summary:

The vapour pressure of the test item Reaction mass of N-butylphthalimide and N-sec-butylphthalimide and N-propylphthalimide was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. The vapour pressure of the test item was 0.03 hPa at 20°C, 0.04 hPa at 25°C and 0.20 hPa at 50°C.
