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:
- 5 Mar 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E 1719-97 “Vapor Pressure Measurement by Ebuilliometry”
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- dynamic method
- Specific details on test material used for the study:
- - Physical state: clear, viscous liquid
- Source and lot/batch No.of test material: Lot 115
- Purity: > 97% - Key result
- Temp.:
- 20 °C
- Vapour pressure:
- < 2 mm Hg
- Conclusions:
- The vapor pressure of 1,1'-isophthaloylbis(2-methylaziridine) is < 2.0 mm Hg at 20 °C.
- Executive summary:
A vapor pressure < 2.0 mm Hg at 20 °C for 1,1'-isophthaloylbis(2-methylaziridine) was reported for the compound. The vapor pressure and temperature were recorded at three points from 65.1 °C to 100.0 °C under the dyanimc method, but boiling was never observed. The measured pressure at 65.1 °C was reported as the upper limit of the vapor pressure. The study was conducted following method ASTM E 1719-97 but was not conducted in accord with GLP guidelines; therefore, the study is considered reliable with restrictions.
- Endpoint:
- vapour pressure
- Type of information:
- not specified
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Qualifier:
- no guideline followed
- GLP compliance:
- no
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- ca. 20 mm Hg
- Conclusions:
- A vapor pressure of ca. 20 mm Hg at 20 °C was reported for 1,1'-isophthaloylbis(2-methylaziridine).
- Executive summary:
A vapor pressure of ca. 20 mm Hg at 20 °C was reported for 1,1'-isophthaloylbis(2-methylaziridine). Only the result was reported on the SDS and no information about the method used was provided; therefore, the reliability of the data is not assignable.

Key value for chemical safety assessment
Additional information
In the key study, a vapor pressure < 2.0 mm Hg at 20 °C for 1,1'-isophthaloylbis(2-methylaziridine) was reported for the compound. The vapor pressure and temperature were recorded at three points from 65.1 °C to 100.0 °C under the dynamic method, but boiling was never observed. The measured pressure at 65.1 °C was reported as the upper limit of the vapor pressure. The study was conducted following method ASTM E 1719-97 but was not conducted in accord with GLP guidelines; therefore, the study is considered reliable with restrictions. In a supporting study, a vapor pressure of ca. 20 mm Hg at 20 °C was reported for 1,1'-isophthaloylbis(2-methylaziridine). Only the result was reported on the SDS and no information about the method used was provided; therefore, the reliability of the data is not assignable.
