Applicant's summary and conclusion
- Conclusions:
- The melting temperature was determined using the capillary method. Melting was observed in the temperature range 191.5 to 197.9 °C at a heating rate of 1 K/min.
- Executive summary:
The melting temperature was determined using the capillary method. Melting was observed in the temperature range 191.5 to 197.9 °C at a heating rate of 1 K/min.
Up to the final melting temperature no decomposition was observed.
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.
