Conclusions:
Solvent Violet 36 is a solid which decomposes before boiling.
Executive summary:

A DTA in the range of 20 to 500°C shows and endothermic process at 215 to 240°C (melting!) and an exothermic process at 360 to 465°C which can attributed to decomposition. No endothermic process attributed to boiling point can be seen.

Description of key information

Solvent Violet 36 is a solid which decomposes before boiling.

Key value for chemical safety assessment

Additional information

Thermal decomposition begins at a temperature of 360°C (method: DTA, heating rate 3 k/min) (Drafz 2018). Up to this point there is no hint for a boiling in the temperature heat/flow diagram. Solvent Violet 36 has no boiling point up to the beginning of the decomposition.
