DSC results:
Lets you freeze
the sample after the first
melting and then heats up
again, then there is the second
melting point of about 16
°C lower. Re-solidification
and heating does
not change anything more. Therefore
the substance after the first melting
and solidification is in another modification as when delivered.
Melting temperature (extrapolated onset temperature)
1. Run | 2. Run | |
1. Measurement | + 73,1 °C | + 56,9 °C |
2. Measurement | + 74,2 °C | + 57,8 °C |
3. Measurement | + 73,8 °C | + 57,7 °C |
4. Measurement | + 73,1 °C | + 57,7 °C |
Summary:
73.6
°C (modification
of the delivery state)
and 57.5 °C
(further modification in
which the modification of the delivery
condition
by melting and solidification converts);
each ± 0.6 °

Applicant's summary and conclusion
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.
