Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
May 18, 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
other: ASTM D2879 - 97 (Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope)
Version / remarks:
2007
Deviations:
yes
Remarks:
Instead of the mercury manometer stipulated, a digital electronic pressure gauge was used for pressure measurement.
GLP compliance:
no
Type of method:
isoteniscope
Key result
Temp.:
20 °C
Vapour pressure:
0.6 hPa
Conclusions:
2-Ethylhexanoic acid, compound with 2-aminoethanol (1:1) has a vapour pressure of 0.60 hPa at 20 °C.
Executive summary:

2-Ethylhexanoic acid, compound with 2-aminoethanol (1:1) was tested according to ASTM D2879 - 97 (Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope) in order to determine vapour pressure. A minor deviation was reported in which a digital electronic pressure gauge was used for pressure measurement in place of a mercury manometer, as stipulated in ASTM D2879 - 97. However, this is not believed to have affected the final result. Vapour pressure was concluded to be 0.60 hPa at 20 °C.
