Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- In-life initiated/completed: 06-March-1997 to 03-July-1997
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Study conducted to OECD 104, EEC Method A.4 and US EPA OPPTS 830.7950 guidelines under GLP and in a trusted laboratory.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Principles of method if other than guideline:
- The gas saturation method used for the vapour pressure determination passes nitrogen as an inert carrier gas over the test substance, thereby saturating the nitrogen with vapour up to the vapour pressure of the test substance and transporting the vapour with the nitrogen flow into a trap. After quantitative determination of the substance in the trap, the partial vapour pressures can be calculated, via the general gas equation, from the volume of nitrogen used to transport this quantity of substance.
The apparatus used for the measurement consists of a gas supply unit, one or two saturator columns, and a trap.
The measurement of the nitrogen flow rate in the apparatus is based on the principle of caloric measurement. By continuously supplying electrical energy via a heating element and measuring the temperature difference established between one measurement point before and one after the heating element, the flow rate is determined in a narrow side stream at a constant split ratio and the quantity of gas is determined by integration over time. - GLP compliance:
- yes
- Type of method:
- gas saturation method

- Executive summary:
The vapour pressure of Spirodiclofen was determined between 25 and 70°C by the gas saturation method. Using the regression coefficients calculated by regression analysis the following vapour pressures were obtained: 3x10-7Pa at 20 °C and 7x10-7Pa at 25 °C.
Reference
The vapour pressures for 20°C and 25°C are also expressed in the form of a gas saturation concentration.
Temperature | vapour pressure | gas saturation concentration |
20 °C | 3x10-7Pa | 0.050 ug/m3 |
25 °C | 7x10-7Pa | 0.100 ug/m3 |
