Melting and Boiling Point (DSC)

The test item showed an endothermic effect in the temperature range of 50 – 170 °C. In the temperature range of 270 – 400 °C an exothermic effect with a mean energy release of -70 J/g could be observed.

No.	Sample weight / mg	Onset of Effect / °C	Range of effect / °C	Weight loss / mg	Atmospheric pressure / hPa	Remark
PN14278	12.75	86.94 ---	50 – 150 (endo) 270 – 390 (exo)	5.33	991.0	Figure 1
PN14279	18.41	94.16 ---	50 – 170 (endo) 290 – 400 (endo)	6.47	991.0	Figure 2

During the heating an endothermic effects was detected, which can be assigned to the drying of the test item (wt. water 9.17%). No melting or boiling of the test item was detected up to its decomposition starting at a temperature of approximately 270 °C.

Applicant's summary and conclusion

Conclusions:

The test item Leuco Sulphur Brown 46 has no boiling point up to its decomposition starting at a temperature of approx. 270 °C as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2., OECD Test Guideline 103 (1995) and EPA OCSPP 830.7220 (1996).
