- Executive summary:
The determination of the vapour pressure of the test item, Fluorosulfonic Adduct, was carried out under GLP compliance, using the static method according to OECD Guideline No. 104 and EU Method A.4 (Vapour pressure).
This method involved placing a quantity of sample in the sample chamber of the glassware and a suitable manometer liquid in the U-tube. The glassware was then positioned in the constant temperature bath set to a desired starting temperature. As the static apparatus and its contents approached temperature equilibrium in the bath, the levels of the manometer liquid were balanced using the positive or negative pressure depending on the direction of displacement. This procedure was repeated until the system achieves temperature and pressure equilibrium (i.e. no significant change in temperature or pressure is observed). The temperature and pressure displayed on the pressure monitors were then recorded. The temperature was subsequently set to a higher temperature (usually 5-25°C higher) and the procedure was repeated until enough data points were obtained.
The vapour pressure analysis was performed three times. Degassing was attempted at ambient temperature, 4°C and -15°C, none of which were successful due to a high rate of loss of test material. The sample was therefore degassed at -25°C, -30°C and -32°C for Test Runs 1, 2 and 3 respectively. However due to the nature of the test material complete degassing was extremely difficult as it was observed that some material was being lost under vacuum.
Extrapolation of the vapour pressure curves to the boiling temperature (stated as 120°C in SDS and TIDS provided by sponsor) gave 1410.17 mbar (1.41 x105Pa), 1220.59 mbar (1.22 x105Pa) and 1688.76 mbar (1.69 x105Pa) for Runs 1, 2 and 3 respectively. However the bending of the curve around the mid-point in Run 3 suggests incomplete degassing (i.e. presence of trapped gasses). As the presence of trapped gasses could influence the vapour pressure results, Run 3 was included in the report for information purpose only. Therefore the result was reported as the mean of Test Runs 1 and 2.
The vapour pressure of the test item at 20°C was 1828.0 Pa (average from two extrapolated values).

Analysis of the vapour pressure curves indicated that Test Run 3 was not as linear, especially when taking boiling point data into consideration. Therefore the result has been reported as the mean of Test Runs 1 and 2.
As part of the data analysis extrapolation of the vapour pressure curve to the boiling temperature of the test item was investigated to ensure linearity. From this extrapolation the vapour pressure at the boiling point was expected to be around 1000 mbar (1x105 Pa). Due to the sub-zero temperatures at which the test material was degassed, the nature of the vapour pressure curve for the effect of incomplete degassing, and any other chemical changes which might not be visually detectible must be considered.
Extrapolation of the vapour pressure curves to the boiling temperature (stated as 120°C in SDS and TIDS provided by sponsor) gave 1410.17 mbar (1.41 x105 Pa), 1220.59 mbar (1.22 x105 Pa) and 1688.76 mbar (1.69 x105 Pa) for Runs 1, 2 and 3 respectively. However the bending of the curve around the mid-point in Run 3 suggests incomplete degassing (i.e. presence of trapped gasses). As the presence of trapped gasses could influence the vapour pressure results, Run 3 has been included in the report for information purpose only.
