TGA EXPERIMENT (PRELIMINARY TEST)

Starting at 200°C, the weight of the sample decreased significantly. At 388°C the sample weight had decreased by 25%. After the experiment, a dark brown residue remained in the sample container.

DSC EXPERIMENT 1

During cooling and heating no effects were observed which were due to melting and/or boiling of the test item. The residue at the end of the test was dark red.

DSC EXPERIMENTS 2 AND 3

During cooling and heating no effects were observed which were due to melting and/or boiling of the test item. The residue at the end of the test was dark red in Experiment 2 and red-brown but darker than at the start of the test in Experiment 3.

DSC curve Experiment 2 during heating: see picture below.

Remark: The observed colour change in each of the tests may be due to reaction/decomposition and/or evaporation of part of the test item. 

Applicant's summary and conclusion

Conclusions:
The substance has no melting point. During DSC experiments, melting of the test item was not observed below the temperature at which reaction/decomposition and/or evaporation started.
Executive summary:

Melting of the substance was investigated in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200. TGA demonstrated that reaction/decomposition and/or evaporation starts at ca. 200°C.

During DSC experiments, melting of the test item was not observed below the temperature at which reaction/decomposition and/or evaporation started. The substance has no melting temperature.
