Purity: Organic part (Na-salt): approx. 83.7 %; All coloured components: approx. 80.54 %; Main component: approx. 59.1 %.
Appearance: Solid, black powder
Storage conditions: At room temperature at about 20 °C
Expiration date: December 31, 2010

Boiling pt.:

> 400 °C

no

Remarks on result:

other: endothermic reaction could be observed, followed by an exothermic reaction

To confirm the result of the preliminary test, a further DSC run was performed. A test item amount of 8.5 mg was heated up from 25 °C to 400 °C at a rate of 10 °C/min. The same broad endothermic reaction could be observed, followed by an exothermic reaction. After the experiment, the sample had lost about 18 % of its mass and the sample was unchanged in appearance.

Conclusions:

The boiling point of the test material was determined to be above 400 °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. To confirm the result of the preliminary test, a further DSC run was performed. A test item amount of 8.5 mg was heated up from 25 °C to 400 °C at a rate of 10 °C/min. The same broad endothermic reaction could be observed, followed by an exothermic reaction. After the experiment, the sample had lost about 18 % of its mass and the sample was unchanged in appearance. In conclusion, FAT 40825/A does not boil under the conditions of the test. The boiling point of the test material was determined to be above 400 °C
