Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- 163.7 °C
- Atm. press.:
- 1 atm
- Decomposition:
- ambiguous
Applicant's summary and conclusion
- Conclusions:
- The ambient temperature range expected during transport, use and/or disposal of ZK 39 211 is much lower than the melting/decomposition temperature. No change of state is expected during such activities nor are there special energy requirements for maintaining ZK 39 211 in the solid state during its transport, use and/or disposal.
- Executive summary:
The melting/decomposition temperature was determined using the capillary method.
Melting/decomposition was observed in the temperature range 163.3 to 173.1 °C at a heating rate of 1 K/min.
Benzoic acid was used as reference material. The melting temperature of Benzoic acid is 122.45 °C ( d'Ans Lax, Taschenbuch für Chemiker und Physiker). Average melting temperature of Benzoic acid: 121.6 °C, standard deviation: 0.2 K, 3 determinations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
