Specific details on test material used for the study:

- Lot: 216-106
- Expiry date: 2018-06-16
- Storage conditions: Keep at room temperature

Key result

Decomposition:

yes

Decomp. temp.:

> 212 - <= 375 °C

Remarks on result:

not determinable

Remarks:

The test substance started to decomposed directly after melting. No boiling was observed up to 375 °C.

Conclusions:

The test substance started to decompose directly after melting. No boiling was observed up to 375 °C.

Executive summary:

The boiling point of the test substance was determined using a method following Siwoloboff with automatic photo-electrical detection according to OECD 103. Three preliminary tests were performed. In these tests no boiling point was observed from melting point (212 °C) up to 375 °C. After the test item melted in the sample tube it began to darken immediately. At the end of each measurement the samples were hardened, their colors darkened and moved to the upper part of the capillary. After the samples cooled to room temperature the appearance of the samples remained above-mentioned, the changes were irreversible. As no boiling point was detected in the preliminary test, the main test was not performed. Boiling point was not observed from melting point up to 375 °C. Based on the visual observations in the preliminary tests the changes of appearance of the test item were irreversible. Therefore it was concluded that the test item started to decompose after melting.
