Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 22 November 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Assessed using appropriate methodology.
- Qualifier:
- according to guideline
- Guideline:
- other: Isoteniscope method
- Deviations:
- no
- Principles of method if other than guideline:
- Analytical Method
Method: Isoteniscope method
Equipment: Isoteniscope with differential manometer
Manometer liquid: Hg
Temperature: 50 °C
Sample handling
Approximately 2.50 g fine powdered test item was weighted into the bulb of the isoteniscope.
Results for vapour pressure determination
The fine powdered, exactly weighted-in test item was introduced into the bulb of the isoteniscope the equipment was placed into a water bath and thermostated to 50 °C. The temperature was controlled during the whole experiment using a digital thermometer. The isoteniscope was attached to a vacuum system, evacuated, and finally filled with nitrogen.
After reaching the thermal equilibrium the manometer was read. No pressure change could be detected. As a minimum of 1 Hgmm can be detected in our system, the vapour pressure of the test item is below 133 Pa. - GLP compliance:
- no
- Type of method:
- isoteniscope
- Specific details on test material used for the study:
- Test substance name: Isophthalonitrile
Chemical name: 1,3-dicyanobenzene
CAS number: 626-17-5
EC number: 210-933-7
LOT number: JB1906150101
Purity: 99.8 % (w/w %)
Appearance: Off white solid flakes
Manufacture date: 15 June 2019
Expiry date: 15 June 2020
Storage condition: Room temperature (15-25oC. below 70 RH%), protected from humidity
Safety Precautions: Routine safety precautions for unknown materials (lab coat. mask. gloves and safety glasses) were applied to assure personnel health and safety. - Key result
- Test no.:
- #1
- Temp.:
- 50 °C
- Remarks on result:
- not determinable because of methodological limitations
- Conclusions:
- The results of the thermo-gravimetric measurement used for the determination of melting point indicate that there is no measureable evaporation/sublimation until above 100°C. Due to the very low volatility, the vapour pressure of this solid material cannot be determined by conventional vapour pressure testing methods. According to the literature (National Institute of Occupational Safety and Health. NIOSH Pocket Guide to Chemical Hazards) - the vapour pressure is at 0.01 Hgmm.
- Executive summary:
The results of the thermo-gravimetric measurement used for the determination of melting point indicate that there is no measureable evaporation/sublimation until above 100°C. Due to the very low volatility, the vapour pressure of this solid material cannot be determined by conventional vapour pressure testing methods. According to the literature (National Institute of Occupational Safety and Health. NIOSH Pocket Guide to Chemical Hazards) - the vapour pressure is at 0.01 Hgmm.
