Applicant's summary and conclusion

Conclusions:

YOFCO MAS boils under degradation at a temperature of 324 °C ± 3 °C.

Executive summary:

The determination of the boiling point/boiling range of the test item was performed according to the EEC Directive 92/69, A.2 "Boiling temperature", December 1992 and to the OECD Guideline No. 103: " Boiling point", adopted July 27, 1995.

A preliminary test was performed with a heating rate of 20 K/min from 25 °C to 400 °C. The first endothermic heat effect was observed between 26 and 40 °C. The second endothermic reaction, evaporation and boiling, was observed at 325.3 °C. After the experiment, the sample had lost about 48 % of its mass and the colour of the sample residue was changed to brown.

In order to determine the boiling of YOFCO MAS more precisely, further DSC-runs were recorded between 25 °C to 400 °C with a heating rate of 10 K/min. In the second run, the boiling was observed at 326.1 C°. During the third run, the boiling was observed at 320.5 °C. After the tests the samples lost 35 % and 31 % of its mass, respectively and the residue sample was coloured brown. The sharp exothermic peak after the endothermic boiling reaction in the DSC-curve indicated the degradation of the test item. This assumption is confirmed by the reduced and brown colored sample residue. YOFCO MAS boils under degradation at a temperature of 324 °C ± 3 °C.
