Preliminary test
From 250°C upwards the weight of the sample decreased significantly. At 305°C and 313°C, the sample weight had decreased by 25% and 70 %, respectively. After the experiment it was observed that the test substance was evaporated from the sample container.
First experiment:
During cooling an exothermic peak was observed between 0°C and -20°C. The effect was obtained due to crystallization of the test substance. During heating a first endothermic peak was observed between 0°C and 50°C. The extrapolated onset temperature of the peak was 20.90°C. The effect was due to melting of the test substance.
Second experiment:
Similar results as with the first experiment were obtained. The extrapolated onset of the first endothermic peak due to melting was 20.13°C.
Applicant's summary and conclusion
- Conclusions:
- The melting temperature of the substance was determined using DSC. The melting temperature of the substance is 21°C (294 K).
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).
