Appearance of the Samples

Before the test the appearance of Sodium (2-butoxyethoxy) acetate was light yellow, viscous liquid. After the experiments the test item blackened and its volume increased in the crucible.

 

Measurement

The evaluation of the data was performed using the software STARe. As result, a thermogram was obtained in which the heat flow of the investigated sample is given as a function of the temperature. By integrating the area under the heat flow signals, the enthalpy of the process was obtained. During the heating the test item showed endothermic signals in the temperature range of approx. 100 - 170 °C what can be associated with the evaporation of test item.

Conclusions:

The test item decomposes up to 500°C.

Executive summary:

A study was performed in accordance with OECD TG 103 in order to determine the boiling point of the test item using the differential scanning calorimetry method. The test was carried out at normal atmospheric pressure. Using a linear heating rate of 10 °C/min the boiling point of Sodium (2-butoxyethoxy) acetate was not observed from room temperature up to 500 °C. Based on the results of the DSC curves and the appearance of test item after the tests, it is concluded the test item decomposes up to 500 °C.

Description of key information

The test item decomposes up to 500°C.
