Reference

Endpoint:

vapour pressure

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2000

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Qualifier:

according to guideline

Guideline:

EU Method A.4 (Vapour Pressure)

Deviations:

no

GLP compliance:

yes

Type of method:

effusion method: vapour pressure balance

Temp.:

20 °C

Vapour pressure:

< 0 hPa

Temp.:

71.34 °C

Vapour pressure:

< 0 hPa

The same value was determined at 20, 25, 50, 70.16 and 71.34°C. The measurement has not been carried out above 75°C due to decomposition.

Conclusions:

The substance has a very low vapour pressure. In the range of 20 to 71.34°C the determined vapour pressure was < 0.00001 hPa.

Executive summary:

According to the EU Method A.4 (vapour pressure balance) the determined vapour pressure was < 0.00001 hPa within a temperature range of 20 to 71°C.
