Vapour pressure
Administrative data
Link to relevant study record(s)
- 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 D 2879 - 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 for pressure measurement, a digital electronic pressure gauge was used.
- GLP compliance:
- no
- Type of method:
- isoteniscope
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.95 hPa
- Conclusions:
- The vapour pressure of N,N’-bis(carboxymethyl)glycine, compound with 2-aminoethanol (1:3) was determined to be 0.95 hPa at 20 °C.
- Executive summary:
N,N’-bis(carboxymethyl)glycine, compound with 2-aminoethanol (1:3) was tested in an experiment to determine vapour pressure according to ASTM D2879 - 97 (Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope). 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 guideline. However, this is not believed to have affected the final result. Vapour pressure was concluded to be 0.95 hPa at 20 °C.

Description of key information
A final vapour pressure of 0.95 hPa at 20 °C was determined for N,N’-bis(carboxymethyl)glycine, compound with 2-aminoethanol (1:3) based on ASTM D2879 - 97 (Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope).
Key value for chemical safety assessment
- Vapour pressure:
- 0.95 hPa
- at the temperature of:
- 20 °C
