- Executive summary:
The melting point of SCARLET RN 1165 has been determined in the current study performed following OECD TG 102 according to GLP. The selected method is Differential Scanning Calorimeter (DSC).
In the preliminary test, the quantities of heat absorbed or released off were measured and recorded at heating rate of 20 K/min from 40°C to 400°C.
Before and after the test, the weight and the appearance of the sample were determined.
An endothermic heat effect was observed between 127 .3 °C and 182.4 °C. Between about 300 °C and 370 °C an exothermic heat effect occurs. After the experiment, the sample had lost about 19.9 % of its mass and the colour of the sample was changed to black. The sample still was a powder and obviously had not been melted and solidified again. The test article does not boil under ambient conditions in the temperature range investigated.
In order to determine the endothermic reaction more precisely, further DSC-runs were recorded between about 145 °C and 200 °C with a heating rate of 1 K/min. In the second run, the endothermic reaction was determined to be between 159. 7 °C and 162.6°C. This is not due to melting of the sample because it was shown to be a non-reversible process. This peak does not appear during the second heating of the same test vessel. The endothermic effect might be caused by a change in crystalline structure, but further evaluation is beyond of the scope of this study. Details were not given in the report. During these runs, the sample lost 5.7 % of its mass. After the measurement the sample was still a powder and coloured red.
In conclusion, SCARLET RN 1165 does not melt under the conditions of the test, meaning that melting point is >400°C.
