Vapour pressure

Link to relevant study record(s)

Reference

Endpoint:

vapour pressure

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

no guideline followed

Principles of method if other than guideline:

This test method is not included into EC Regulation 761/2009, Guideline A.4 Vapour Pressure [9.4], nor into OECD Guideline 104 Vapour pressure [9.5]. Nevertheless, this method was taken because for substances which are thermally unstable and contain impurities it is a more suitable method than the other listed in the above-mentioned guidelines. It is expected that this method will be included into EC Guideline A.4 in the near future. A request for inclusion was sent to the Dutch National Coordinator for Test Methods.

GLP compliance:

no

Type of method:

other: Differential Scanning Calorimetry under an applied constant pressure

Key result

Temp.:

25 °C

Vapour pressure:

< 0 Pa

The calculated vapor pressure of the test substance at 25°C (P) is below 1.0·10-8 Pa (corrected for worst case error in ΔHvap. ΔHvap. = 117000±3000 J/mole). Based on extrapolation of data measured in the DSC, it can be concluded that the vapor pressure of the test substance is far below 0.01 Pa.

Conclusions:

The vapor pressure of test substance at 25°C is derived from calculated and experimental data. The vapor pressure of test substance at 25°C is well below 0.01 Pa or 0.1 μBar (In the range of 1·10-9 - 1·10-8 Pa).
