Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- < 223 K
Any other information on results incl. tables
The main test was not carried out since the two preliminary tests did not show any crystallisation down to 223 K and no seed of crystalline material could be prepared.
Further, a 15 -mL sample was kept in a freezer at 252 K (-21°C) for 7 days without having solidified.
Applicant's summary and conclusion
- Conclusions:
- It can be concluded that the freezing point of GR-85-2517 is below 223K, i.e. below -50°C
- Executive summary:
The freezing point of GR-85 -2517 was measured according to the OECD guideline No. 102 (method of the freezing temperature). The result can be expressed as follows:
Freezing point of GR-85 -2517: below 223 K (below -50°C)
