- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018.2.27 - 2018.4.5
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- not specified
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- distillation method
- Specific details on test material used for the study:
- Sample name : supplied as a name of ESA
Appearance : White powder
Chemical name : 1,3,2-Dioxathiolane, 2,2-dioxide
Cas No. : l 072-53-3
Purity: 100 % - Atm. press.:
- 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- > 170 °C
- Conclusions:
- Boiling point was measured by using a general distillation apparatus under atmospheric pressure. Conclusively, boiling point of ESA was not determined at 101.3 kPA. The sample was degraded above 170 ºC (443 K).
- Executive summary:
Boiling point was measured by using a general distillation apparatus under atmospheric pressure. Conclusively, boiling point of ESA was not determined at 101.3 kPA. The sample was degraded above 170 ºC (443 K).

Distillation method can measure up to a maximum of 250 ºC.
As a result of the test, the sample was not distilled but decomposed at 170 ºC and the color of the test material started to change from colorless to brown at 170 ºC.
Therefore, ESA was not distilled at 170 ºC and decomposed above 170 ºC.
Description of key information
Boiling point was measured by using a general distillation apparatus under atmospheric pressure. Conclusively, boiling point of ESA was not determined at 101.3 kPA. The sample was degraded above 170 ºC (443 K).
