Key result
Decomposition:
yes
Decomp. temp.:
ca. 210 °C
Remarks on result:
not determinable

Preliminary test: At about 210 °C the test item started to turn black and decomposed. No melting point was observed.

Conclusions:
At about 210 °C the test item started to turn black and decomposed. No melting point was observed.
Executive summary:

The test was carried out according to OECD guideline 102 and EC method A.1. Capillary tubes filled with the test item were heated in a metal block. The test item started to decompose at about 210 °C, hence no melting point could be observed.
