yes
Decomp. temp.:
ca. 350 °C
Remarks on result:
other: Approximately 68 % of the test item remained at 400 °C.

RESULTS

- Thermograms for determinations 1 and 2 are shown in Figures 3.1 and 3.2 (attached).

- Thermographic data are shown in Table 3.3 (below).

- After being heated to 400 °C, the residues of the two determinations had lost 33 % and 32 % of their original weight respectively.

- Overall result: partial boiling from approximately 280 °C (553 K) with decomposition from approximately 350 °C (623 K).

Conclusions:
The boiling point of the test item was assessed in accordance with OECD Guideline 103. The test item was determined to partially boil from approximately 280 °C (553 K) at 101 kPa with decomposition from approximately 350 °C (623 K) at 101 kPa. At 400 °C approximately 68 % of the test item remained.
Executive summary:

GUIDELINE

The determination was carried out by differential scanning calorimetry using a procedure designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

RESULTS

The test item was determined to partially boil from approximately 280 °C (553 K) at 101 kPa with decomposition from approximately 350 °C (623 K) at 101 kPa. At 400 °C approximately 68 % of the test item remained.

Description of key information

The boiling point of the test item was assessed in accordance with OECD Guideline 103.  The test item was determined to partially boil from approximately 280 °C (553 K) at 101 kPa with decomposition from approximately 350 °C (623 K) at 101 kPa. At 400 °C approximately 68 % of the test item remained.
