- yes

- Conclusions:
- No normal boiling point could be observed.
Possible interpretation of the endothermal peak at 313 °C:
• A partial boiling of the main compound starts at around 312 °C, probably already associated with decomposition.
• This peak may be a result of a partial boiling of the decomposed test item. The beginning of decomposition cannot be defined by these measurements. As a rough estimate, decomposition starts probably at around 240 °C - Executive summary:
The boiling point of MDEA-Esterquat C18 unsatd. was determined according to OECD TG 103 / EU method A.2 using differential scanning calorimetry.
No normal boiling point could be observed.
Possible interpretation of the endothermal peak at 313 °C:
• A partial boiling of the main compound starts at around 312 °C, probably already associated with decomposition.
• This peak may be a result of a partial boiling of the decomposed test item. The beginning of decomposition cannot be defined by these measurements. As a rough estimate, decomposition starts probably at around 240 °C
Reference
Preliminary thermogravimetric measurement
A preliminary thermogravimetric measurement was performed over a temperature range from room temperature to 600 °C.
The sample was purged 30 minutes with nitrogen before the start of the measurement (heating ramp).
Four steps were registered with maxima at 139 °C, 186 °C, 320 °C and 411 °C. A total mass loss of ca. 97 % at the final temperature could be observed. There was a black residue.
Mass loss in the range until 155 °C: 0.7 %
Mass loss in the range from 155 °C to 225 °C: 0.8 %
Mass loss in the range from 225 °C to 355 °C: 43.6 %
Mass loss in the range from 355 °C to 600 °C: 51.9 %
The course of the thermogravimetric curve and the remaining residue suggest decomposition of the test item.
DSC measurements
Upon heating, a broad endothermic peak with three maxima at -63 °C, -41 °C (major) and ca. -30 °C was registered. The endothermic peak exhibits an atypical shape with several maxima and can probably be assigned to a melting range between ca. -76 and -27 °C (extrapolated Onset/Endset-Temperature).
Upon further heating several smaller endothermal signals with maxima at ca. 40 °C, ca. 96 °C, ca. 133 °C and ca. 192 °C were registered, which cannot be categorized. This could be phase changes (e.g. partial melt (the sample is a pasty solid)), as well as moisture release. It is to be noted that a thermogravimetric test with an “open” crucible (lid with big hole) will yield a different curve than a measurement with a lid with one 50 μm hole.
Upon further heating a broad and noisy endothermal peak with a very sharp maximum at 313 °C and an extrapolated onset temperature of 312 °C was registered. Reweighing after the measurement the sample had lost between 60 and 78 % of its mass, there was a brown residue visible. This endothermic peak reveals an unusual shape for a boiling point. This suggests a possible boiling of the main compound with simultaneous decomposition or may be a result of a partial boiling of the decomposed test item. The extrapolated onset temperature can therefore not be determined with sufficient probability to establish the boiling temperature.
