Vapour pressure

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

vapour pressure

Type of information:

experimental study

Adequacy of study:

supporting study

Reliability:

4 (not assignable)

Rationale for reliability incl. deficiencies:

documentation insufficient for assessment

Qualifier:

no guideline followed

Principles of method if other than guideline:

Determination with the "gas saturation method" according to a method developed by Rittfeldt L. 2001. Analytical Chemistry 73(11), 2405-2411

GLP compliance:

no

Temp.:

22 °C

Vapour pressure:

1.04 Pa

Conclusions:

The vapour pressure of the substance is about 1 Pa at 22 °C and atmospheric pressure.

Executive summary:

The vapour pressure of the substance was determined by the gas saturation method in a temperature range from -12 to 103 °C. A fused-silica column coated with the compound was placed in a GC and the vapour pressure was determined from the detector signal or by sampling on Tenax tubes. The vapour pressure was 1.04 Pa at 22 °C and 1013 hPa.

Vapour pressure in Pa at 25 °C	3.8

A total of six runs were completed for the main sequence. Equilibrium with regard to vapour pressure was reached over the six runs. All six runs have been used to calculate the definitive vapour pressure value.

Conclusions:

The vapour pressure of the substance is 3.8 Pa at 25 °C.

Executive summary:

The vapour pressure of the substance was determined under GLP in accordance with EU Method A.4 by applying the vapour pressure balance method. A total of six runs were completed and equilibrium with regard to the vapour pressure was reached over the six runs. The average value for the vapour pressure measured in 6 runs was 3.8 Pa at 25 °C.

Description of key information

Additional information

The vapour pressure of the substance was determined under GLP in accordance with EU Method A.4 by applying the vapour pressure balance method. A total of six runs were completed and equilibrium with regard to the vapour pressure was reached over the six runs. The average value for the vapour pressure measured in 6 runs was 3.8 Pa at 25 °C.

This value corresponds well to a published vapour pressure value of 1.04 Pa at 22 °C.
