Not determined (not distilled at 170 ºC, degraded above 170 ºC)

Not determined (not distilled at 443 ºC, degraded above 443 ºC)

2

Not determined (not distilled at 170 ºC, degraded above 170 ºC)

Not determined (not distilled at 443 ºC, degraded above 443 ºC)

Average

Not determined (not distilled at 170 ºC, degraded above 170 ºC)

Not determined (not distilled at 443 ºC, degraded above 443 ºC)

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.

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).
