- Executive summary:
During this study, the vapor pressure of the test item MEXORYL SBU has been determined using the gas saturation method. The vapor pressure of MEXORYL SBU was measured at test temperatures of 20 °C, 30 °C and 40 °C and was determined to be 1.2 x 10-2Pa at 20 °C, 4.1 x 10-2Pa at 30 °C, 1.1 x 10-1Pa at 40 °C. The vapor pressure of MEXORYL SBU at 25 °C was interpolated from the vapor pressure curve and was calculated to be 2.2 x 10-2Pa at 25 °C.
Reference
The vapor pressure of MEXORYL SBU was determined at 20 °C, 30 °C and 40 °C. The vapor pressure of MEXORYL SBU at 25 °C was calculated by interpolation from the vapor pressure curve.
The tabulated values represent rounded results that were obtained by calculation using the exact raw data. The vapor pressure of MEXORYL SBU was determined at 20 °C, 30 °C and 40 °C. To ensure saturation control, three different flow rates were used at each temperature. It can be clearly seen that higher flow rates did not lead to lower vapor pressures, which means that the nitrogen was saturated with test item under the conditions of the test.
The experimental results lead to the conclusion that the vapor pressure of the test item MEXORYL SBU is:
1.2 x 10-2Pa at 20 °C
4.1 x 10-2Pa at 30 °C
1.1 x 10-1Pa at 40 °C
The vapor pressure at 25 °C was interpolated from the vapor pressure curve and was calculated to be 2.2 x 10-2
The trapping efficiency of the test item MEXORYL SBU in the first cooling trap was very good. More than 98.3% of the test item was trapped in the first cooling trap.
The calibration data for test item-standards is given in Figure 4 and Table 5.The r² fit for the calibration data for test item-standards was 1.0000 (optimum 1.0000). This reflects the suitability of the HPLC-system within the calibration range of 0.585 µg/mL to 117.0 µg/mL of the test item. The good reproducibility and independency of the results from the flow rate led to the conclusion that the results of the vapor pressure determination of the test item MEXORYL SBU are reliable.
