Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- <= -90 °C
- Remarks on result:
- other: Not observed above -90°C
Any other information on results incl. tables
No effects due to crystallization and/or melting of the test substance were observed with a temperature programme that was cooled down to -90°C.
An additional experiment was performed to investigate whether the test substance melts at low temperatures. The test substance was stored in a freezer at -15°C to -30°C for 7 hours. The test substance was still a liquid. Subsequently, the vessel was placed overnight in a freezer at -75°C to -90°C. Either at this temperature, the test substance was a liquid. From this it was concluded that the crystallization of the test substance does not occur at temperatures of above -75°C.
Applicant's summary and conclusion
- Conclusions:
- The melting temperature of the reaction mass containing mainly 2-chloropropene were determined using DSC.
Freezing and/or melting of the test substance was not observed at temperatures of above -90°C (183K).
