- Executive summary:
The vapour pressure was determined using EU Method A.4 guideline using the vapour pressure balance method under GLP. Measurements being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. The temperature of the sample was controlled electronically. The mass and temperature readings were recorded automatically into a computer file. The difference in mass readings with the orifice covered and uncovered is proportional to the vapour pressure at the given oven temperature. Temperature and pressure readings were taken between 25 and 35°C with a one-hour dwell time at 25°C between runs. The vapour pressure of the test item was extrapolated from the vapour pressure curve (log10Vpversus 1/T). The mean vapour pressure based on nine runs was 0.149 Pa at 25°C.

Note the first of ten runs was excluded from assessment as the system had not reached equilibrium (details provided in the full study report).
The slope and intercept of the nine (9) individual runs for theplot ofLog10Vp(Pa) versus reciprocal of temperature (K) is recorded in the full study report. A total of 10 runs were completed for the main sequence. Run 1 was not utilised as the sample was still equilibrating.With regard toequilibrium, this has been assessed to have been reached over runs 1 to 9 (actual #2 to #10) which were used to calculate the vapour pressure. There was no evidence of decomposition during the course of the test (no change in appearance).
Results:
The test item appearance was recorded before and after testing as a clear, pale yellow liquid, thus no change in appearance of the test item occured under the conditions used during the study.
Recorded temperatures, mass differences and the resulting calculated values of vapor pressure are shown in the following tables:

A plot of Log10(vapor pressure (Pa)) versus reciprocal temperature (1/T (K)) for Run 7 gives the following statistical data using an unweighted least square treatment.
Slope: -2.73 x 103
Standard error in slope: 115
Intercept: 8.27
Standard error in intercept: 0.375
The results obtained indicate the following vapour pressure relationship:
Log10(Vp (Pa)) = -2.73 x 103 / temp (K) + 8.27
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -0.872.

Additional information
Key study 1: EU Method A.4, 2019 : The vapour pressure was determined using EU Method A.4 guideline using the vapour pressure balance method under GLP. Measurements being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. The temperature of the sample was controlled electronically. The mass and temperature readings were recorded automatically into a computer file. The difference in mass readings with the orifice covered and uncovered is proportional to the vapour pressure at the given oven temperature. Temperature and pressure readings were taken between 25 and 35°C with a one-hour dwell time at 25°C between runs. The vapour pressure of the test item was extrapolated from the vapour pressure curve (log10Vpversus 1/T). The mean vapour pressure based on nine runs was 0.149 Pa at 25°C.

Measurements being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. The temperature of the sample was controlled electronically. The mass and temperature readings were recorded automatically into a computer file. The difference in mass readings with the orifice covered and uncovered is proportional to the vapour pressure at the given oven temperature. Temperature and pressure readings were taken between 28 and 38°C with a one-hour dwell time at 25°C between runs. The vapour pressure of the test item was extrapolated from the vapour pressure curve (log10Vpversus 1/T). The mean vapour pressure based on seven runs was 0.132 Pa at 25°C
Conclusion : the vapour pressure of the substance is 0.132 Pa at 25°C (2021)
