Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Sublimation:
no
Conclusions:
The test substance (EC: 433-100-1) started to decompose or react at about 240 °C (513 K) using a heating rate of 10 K/min.
Executive summary:

The determination of the melting point / melting range of the test substance (EC: 433-100-1) was performed in accordance with OECD guideline No. 102 and EU method A.1. The determination of the melting point / melting range was performed in duplicate by visual judgment using the capillary method. Two independent aliquots of the test substance (EC: 433-100-1) were heated each in a glass capillary in the melting point from room temperature with a heating rate of 10 K/min. In the preliminary test, the test substance (EC: 433-100-1) was started changing the colour from white to brown at a temperature of about 240 °C (513 K). This observation could be deduced from a reaction or decomposition of the test substance. After cooling down, a dark residue remained. No further experiments were performed because no phase transition of the test substance (EC: 433-100-1) was observed up to the decomposition or degradation of the test substance.
