Any other information on results incl. tables

The determination of the boiling point / boiling range of the test item was performed according to the EEC Directive 92/69 and Council Regulation (EC) No. 440/2008, A.2 “Boiling temperature" and to the OECD Guideline No. 103: "Boiling point", adopted July 27, 1995.

Preliminary Test            

The DSC-curve of the preliminary test (heating rate of 20 °C/min from 25 °C to 400 °C) is shown in attached Figure1. An endothermic heat effect was observed at about 247.4 °C. After the experiment, the sample had lost 95.6% of its mass and a small amount of a dark brown residue remained in the sample cup

Main Tests

In order to determine the boiling point more precisely, further DSC-runs were recorded between 150 °C and 320 °C with a heating rate of 10 °C/min. During these runs, the boiling point was determined to be 245.6 °C and 245.8 °C. The samples lost 95.7% and 94.2% of their mass, respectively. After the measurements a small amount of a brownish residue remained in the sample cup. The DSC curve of the first main test is given in attached Figure 2. The results of the thermal analysis are summarized in Table 1.
