Additional information
Within RCC Study number 742397 (Jan. 2000) the melting point for the submission substance was determined by differential scanning calorimetry according to OECD 102 and EU-method A.1 compliant with GLP. As a result of three test runs (preliminary test; two test runs within the main test), the melting point must be above the thermal decomposition temperature within ambient air of ca. 350°C. The sample lost between 39% and 50% of its mass till the end of the runs and was coloured black, foamed and carbonized, without melting.
Differential scanning calorimetry is one of the methods foreseen within OECD test guideline 103 (boiling point). As such, the boiling point was not experimentally accessible. Therefore, the (theoretical) boiling point was calculated using Meissner's method (Lyman et al., 1990):
(theoretical) Boiling point (calculated according to Meissner's method): 656°C

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).
