Key result

Boiling pt.:

> 360 °C

Atm. press.:

ca. 1 atm

Decomposition:

yes

No.	Weight (mg)	Temperature range (°C)	Type of effect	Energy (J/g)
1	20.6	215 -240 362 - 465	endothermic exothermic	-190
2	28.4	215 -240 360 - 465	endothermic exothermic	-190

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.

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.
