- Conclusions:
- Calculation of the vapor pressure of the substance at 25 °C by interpolation based upon the simplified Clausius-Clapeyron equation resulted in a vapor pressure of 1.7 x 10E-1 Pa at 25 °C.
- Executive summary:
During this study, the vapor pressure of the test item CA3688A has been determined using the gas saturation method. The vapor pressure of the substance was measured at test temperatures of 20 °C, 30 °C and 40 °C and was determined to be 1.1 x 10-1Pa at 20 °C, 3.8 x 10-1Pa at 30 °C, 1.2 x 100Pa at 40 °C, and 1.7 x 10-1Pa at 25 °C (by interpolation).
Reference
The experimental parameters for the performance of the vapor pressure determination are summarized in Table 1. The results and the amount of nitrogen used to calculate the vapor pressure of the individual experiments are summarized inTable 2. The tabulated values represent rounded results that were obtained by calculation using the exact raw data. To ensure saturation control, three different flow rates were used at each temperature. From Table 1 and Table 2 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.
