Ident No.	Test item / mg	Starting temperature / °C	Final test temperature / °C	Temperature range (endo-thermal) / °C	Onset (boiling) / °C	Crucible	Observations after the measurement
36241	24.45	25	500	60 to 170	112.2	glass, open	Mass loss: 67 %
36243	38.50	25	200	80 to 190	115.2	glass, open	Mass loss: 67 %

Table 2: Results of the capillary method

No.	Set point / °C	Heating rate / K/min	End point / °C	Remarks
1	50	10	200	Approx. 92°C: bubble formation started Approx. 117°C: rate of bubble formation increased Approx. 122°C: boiling Approx. 163°C: condensate observed at the top of capillary Approx. 178°C: formation of solid particles Approx. 182°C: test item completely solid

The capillary method measurement showed that the boiling of the test item started at approximately 120°C.

Under consideration of the results from the DSC measurements and the capillary method, it was concluded that the test item had a boiling range of 112 to 116°C. The boiling was incomplete (mass loss: 67 %).

Conclusions:

Dihydrogen tetrachloropalladate has a boiling range of 112 to 116°C. The boiling was incomplete (mass loss: 67 %).

Executive summary:

Nau (2017) is a GLP-compliant study following OECD guideline 103 and EU method A2. It is considered suitable for use as the key study for this endpoint. Dihydrogen tetrachloropalladate has a boiling range of 112 to 116°C. The boiling was incomplete (mass loss: 67 %).
