Table 4.3/1: Thermographic Data

Thermograms from Determinations 1, 2, 3 and 4 are attached.

Thermal Event	Interpretation	Temperature [°C (K)]
		Determination 1	Determination 2	Determination 3	Determination 4
Broad endotherm	Onset of boiling	170.36 (443.51)	165.37 (438.52)	160.17 (433.32)	155.17 (428.32)

 

Atmospheric pressure: 102 to 103 kPa

After being heated to 400 °C, the residue had lost 45 % and 48 % of its original weight for Determinations 3 and 4 respectively.

Overall result: onset of boiling from approximately 155 °C (428 K)

Discussion

The initial endotherm in the thermograms at approximate 40 °C was the test item melting. As the test item was a complex mixture, the boiling event occurred gradually over a wide temperature range. Therefore, the test result was taken as the approximate temperature of when the test item first showed thermographic signs of boiling. As approximately 50 % remained after heating to 400 °C, complete boiling of the test item had not occurred.

Conclusions:

The boiling point of the test item was assessed in accordance with OECD Guideline 103 and has been determined to boil from approximately 155 °C (428 K) at 102 to 103 kpa.

Executive summary:

GUIDELINE

Boiling point was determined using a method designed to be comptible with Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995, and EU Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.

METHOD

Four main runs were performed using differential scanning calorimetry, and an overall result was reported.

RESULTS

As the test item was a complex mixture, the boiling event occurred gradually over a wide temperature range. Therefore, the test result was taken as the approximate temperature when the test material first showed thermographic signs of boiling. As approximately 50 % remained after heating to 400 °C, complete boiling of the test item had not occurred.

CONCLUSION

The test item has been determined to boil from approximately 155 °C (428 K) at 102 to 103 kPa.

Description of key information
