- Conclusions:
- The present study was performed in order to determine the boiling point of Rhamnolipid. The test item decomposes at approx. 170°C at atmospheric pressure.
- Executive summary:
In the present study the boiling point of the test item was determined by using differential scanning calorimetry according to Regulation EC NO. 440/2008 Method A.2 and OECD Test Guideline 103 (revised 1997). The test item was weighed out into aluminum crucibles under air and two tests with about 4 mg of the test item were performed. The prepared aluminum crucibles (crucible with test item and reference crucible) were placed in the DSC apparatus and subsequently the temperature was increased up to 500 °C at a constant heating rate of 10 K/min under an inert atmosphere. 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. The test item boils under decomposition at approx. 170°C at atmospheric pressure.
