- Analytical purity: 95.11%
- Expiration date of the lot/batch: 31 May 2017

Key result

Decomposition:

yes

Decomp. temp.:

200 °C

Remarks on result:

other: Boiling of the test substance was not observed below this temperature.

During heating in Experiment 1, an endothermic peak between 225 °C and 325 °C was observed. In Experiment 2, a closed sample container was applied to investigate whether the peak between 225 °C and 325 °C could be related to boiling. An exothermic peak followed by an endothermic peak between 225 °C and 350 °C was observed. After Experiments 1 and 2, a small amount of black residue remained in the sample container. Based on visual observations, the endothermic effects were most likely due to reaction and/or decomposition of the test item.

Experiments 3 and 4 were performed to investigate reaction and /or decomposition of the test item. Experiment 3 was stopped at 315 °C and Experiment 4 was stopped at 300 °C. After Experiment 3 it was observed that the test item had evaporated from the sample container. Therefore no conclusion on boiling point could be drawn from this experiment. After experiment 4, an off white/yellowish molten residue remained in the sample container. It demonstrated that reaction and/or decomposition of the test item was the reason for the endothermic effect.

Conclusions:

Due to decomposition starting at 200 °C, FBSEE diol has no boiling temperature as determined by EU Method A.2.

Executive summary:

The boiling point of FBSEE diol was tested using differential scanning calorimetry (DSC). Boiling of the test substance was not observed below 200 °C (when decomposition started). Based on this, the test substance has no boiling temperature. The study was conducted in accordance with EU Method A.2 and was GLP compliant; therefore the study is considered reliable without restrictions.

The boiling point of FBSEE diol is 286.8 °C according to a method similar to ASTM D1120 -94. Limited details are available with the report; therefore, the results are considered reliable with restriction.

Description of key information

Due to decomposition starting at 200 °C, FBSEE diol has no boiling temperature (EU Method A.2).

Additional information

In the key study, the boiling point of FBSEE diol was tested using differential scanning calorimetry (DSC). The study was conducted in accordance with EU Method A.2 and was GLP compliant; therfore the study is considered reliable without restrictions. In a supporting study, the boiling point of FBSEE diol was determined as 286.8 °C according to a method similar to ASTM D1120-94. The results are considered reliable with restrictions; however, because the boiling point was extrapolated from temperatures below 200 °C, the result is not considered further.
