Specific details on test material used for the study:
Aspect: colourless to pale yellow liquid
Lo No. TQT 0300497
Purity (GC): 65.7% E isomer, 25.2% Z isomer
Expiration date: November 28, 2004
Key result
Melting / freezing pt.:
< -50 °C
Atm. press.:
1 atm

No crystallisation was observed during the first and second preliminary tests. That's why the main test was not carried out since the two preliminary tests did not show any crystallisation down to 223K and no seed of crystalline material could be prepared.

Conclusions:
From the above-described tests, it can be concluded that the freezing point of Karmalone is below 223K, i. e. below -50°C.
Executive summary:

The freezing point of Karmalone was measured according to the OECD guideline No. 102 (method of the freezing temperature). The result can be expressed as follows:

Freezing point of Karmalone : below 223 K (below -50°C).

Description of key information

The freezing point of Karmalone was measured according to the OECD guideline No. 102 (method of the freezing temperature).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
