Key result
Atm. press.:
>= 1 019.8 - <= 1 020.2 hPa
Decomposition:
no
Remarks on result:
not determinable
Remarks:
No melting point in the temperature range 25 °C - 500 °C

In the temperature range of 390 °C – 450 °C, an endothermic effect could be detected. After the measurement the colour of the test item changed from yellow powder to grey sintered solid.

Results of the DSC-measurements

Sample weight / mg Start of Effect / °C Range of effect / °C Weight loss / mg Atmospheric pressure / hPa
16.64 390 390 – 450 (endo) --- 1019.8
15.76 390 390 – 450 (endo) --- 1020.2

The test item showed no distinct endothermic signal in the test that can be assigned with a boiling of the test item. The very small and broad endothermic effect is caused by another endothermic process (e.g. sintering, gas evolution). Therefore the test item has no boiling point in the temperature range 25 °C - 500 °C.

Conclusions:
The test item Potassium hexacyanocobaltate (III) has no boiling point from 25 °C up to a temperature of 500 °C at atmospheric pressure (1020 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and A.2., OECD Test Guideline 102 and 103 (1995).
