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

Temperature (°C)	Pressure (mm Hg)
65.1	2.0
83.1	2.1
100.0	2.2

The substance was never observed to be boiling during the study.

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.

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.

Description of key information

The vapor pressure of 1,1'-isophthaloylbis(2-methylaziridine) is < 2.0 mm Hg at 20 °C.

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.
