Preliminary test:

The preliminary test was performed as described. Crystallisation was observed at -12.0°C.

Main test:

Crytallisation was observed at -11.9°C (261.25K)

Conclusions:
The freezing point of Amyl salicylate was determined to be -11.9°C using crystallisation apparatus.
Executive summary:

The freezing point of Amyl Salicylate was measured according to the OECD Guideline No. 102. Crystallisation was observed at - 11.9°C (261.25 K). Therefore the freezing point was determined to be -11.9°C.

Description of key information

The freezing point was determined to be -11.9°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
