Type of method:
thermal analysis
Remarks:
Differential Thermal Analysis
Melting / freezing pt.:
190 °C
Atm. press.:
1 017 hPa
Conclusions:
A melting point of 190 °C was determined for Solvent Violet 13 at 1017 hPa.
Executive summary:

The test was performed as stipulated in EC Test Procedure A.1 'Melting/Freezing Temperature' – ASTM E 537 ‘Standard method for assessing the thermal stability of chemicals by methods of differential thermal analysis’.

The Differential Thermal Analysis (DTA) records the difference of the temperature of the substance Solvent Violet 13 and an empty measuring cell. The substance and reference cell were subjected to the same controlled temperature programme. The sample (12.9 mg, 15.5 mg and 14.7 mg) was heated in a glass vessel at a linear rate of 1 K/min. The measurement was recorded electronically.

A melting point of 190 °C was determined for Solvent Violet 13 at 1017 hPa.
