- Conclusions:
- To Vulkacit P extra N a vapour pressure of 10E-5 Pa at 50 °C was estimated by applying Antoine equation on measured values determined according to OECD guideline 104.
- Executive summary:
The purpose of this study was the determination of the vapour pressure of Vulkacit P extra N according to European Commission Regulations (EC) No. 440/2008 and No. 761/2009, A.4. Vapour pressure: Effusion method and OECD test guideline, OECD 104 Vapour pressure.
The method is based on the estimation of the mass of test item flowing out per unit of time of a Knudsen cell in the form of vapour, through a micro-orifice under ultra-vacuum conditions.
The recommended range of the vapour pressure for this method is 10-5to 10-2hPa and for the temperature between approximately 0 and 150 °C. This method is recommended for pure substances. For mixtures the results are only valid for the given parameters, e.g. molecular mass.
Before the measurement the test item was was degased at 50 °C for 6 hours.The vapour pressure was measured in the temperature range of 80 °C to 120 °C. After the measurement a mass loss of < 0.1 % (w/w) was determined.
Since the test did not yield vapour pressures sufficiently high to extrapolate to 20, 25 and 50 °C these values were estimated according to the Antoine equation.
In order to ensure a conservative approach the vapour pressures were rounded up to the next order of magnitude in order to obtain final upper limit values for the vapour pressure.
T / °C p / hPa p / Pa 20 < 1 X 10-9 < 1 X 10-7 25 < 1 X 10-9 < 1 X 10-7 50 < 1 X 10-7 < 1 X 10-5
Reference
Before the measurement the test item was was degased at 50 °C for 6 hours.The vapour pressure was measured in the temperature range of 80 °C to 120 °C. After the measurement a mass loss of < 0.1 % (w/w) was determined.
Measured vapour pressures and corresponding temperatures
Temperature/ °C | Vapour pressure / hPa |
70 | 1.3 X 10-5 |
80 | 5.3 X 10-6 |
90 | 3.1 X 10-6 |
100 | 4.5 X 10-6 |
110 | 6.4 X 10-6 |
120 | 7.2 X 10-6 |
The data points measured between 80 °C and 120 °C were below the detection limit of 1 x 10-5 hPa.
Since the test did not yield vapour pressures sufficiently high to extrapolate to 20, 25 and 50 °C these values were estimated. According to the Antoine equation, the vapour pressure can be calculated.
In order to ensure a conservative approach the vapour pressures were rounded up to the next order of magnitude in order to obtain final upper limit values for the vapour pressure.
