Description of key information
27 -61°C
Key value for chemical safety assessment
Additional information
The substance was tested for its melting point according to the OECD 102 and internal SOP-STR28 by using the Differential Scanning Calorimetry. The substance presents a melting range of 27 -61 °C (onset 27.2 °C, ΔΗ=37.4 J/g), followed by the boiling of the substance between 100 -315 °C (onset 218.5 °C, ΔH = 389.8 J/g) and an endothermic decomposition of the residue from 315 -436 °C (onset 359.8 °C, ΔH=176.0 J/g).
Melting range: 27-61 °C, at 1013 hPa and 20 °C.
Available data in literature support the melting range obtained by DSC, since the melting range indicated in a report on the assessment of the substance is between 48 -53 °C ( CTFA, 1978; Elder RL (ed), 1980; Schlossman, M.L. & McCarthy, J.P. 1978).

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.
