- Key result
- Melting / freezing pt.:
- < -65 °C
- Atm. press.:
- ca. 1 013.25 hPa
- Decomposition:
- no
- Conclusions:
- The melting point of the test item was determined to be below -65°C.
- Executive summary:
A study was conducted according to OECD test guideline 102, Directive 92/69/EWG method A.1. The melting point / melting range was determined by placement of the sample into a cooling bath. The test item was cooled with dry ice until -65 °C without freezing of the sample. The test item had melting temperature below - 65 °C.
Reference
25 mL of the test item were placed in an flask. The flasked was closed with a plug with two holes. Through the holes a thermometer and a stirrer was inserted. The flasked was placed in an acetone cooling bath and slowly cooled down by the addtion of dry ice.
Description of key information
The test item had a melting point <-65 °C.
Key value for chemical safety assessment
