EC number: 200-735-9 | CAS number: 70-47-3
decomposition >250°C, no boiling point; OECD Guideline 103; RL1; GLP
The final DSC measurements were performed in the temperature range from 20 - 340 °C. To determine a possible boiling point more precisely a crucible lid with a hole of 50 µm diameter was used in the measurements. The small hole causes the generation of a defined atmosphere at constant pressure inside the crucible and allows measurements at near equilibrium conditions, thus preventing evaporation of the test material before reaching the boiling point.
Two endothermic peaks could be observed (peak maxima: 109 °C/242 °C [first run] resp. 109 °C/ 240 °C [second run]). These two peaks correlate with maxima observed during the thermogravimetric measurement. Upon further heating the DSC-curve showed no more sharp peaks but the typical fluctuating course of decomposition.
