First test: 208.1 °C at 1019 hPa

Second test: 207.8 °C at 1019 hPa

Run 2, batch 56631: temperature range 200 °C to 220 °C, heating rate 1 °/min:

First test: 206.7 °C at 1019 hPa

Second test: 207.7 °C at 1019 hPa

Run 3, batch 58208: temperature range 200 °C to 220 °C, heating rate 1 °/min:

First test: 207.8 °C at 1019 hPa

Second test: 208.0 °C at 1019 hPa

1. Run 208.1 °C

1. Run 207.8 °C

2. Run 206.7 °C

2. Run 207.7 °C

3. Run 207.8 °C

3. Run 208.0 °C

Mean Value: 207.7 °C

with standard deviation 207.7 °C +/- 0.5 °C (480.85 +/- 0.5 K)

Conclusions:
Under the study conditions, the boiling temperature of the test substance has been determined to be 207.7 °C +/- 0.5 °C (480.85 +/- 0.5 K) at 1019 hPa.
Executive summary:

A study was conducted to determine the boiling point of the test substance according to OECD Guideline 102 and EU Method A.1. The measurements were carried out by using a capillary tube in a metal block described by OECD and EC. Three runs with two replicates each were performed at temperature range of 200 °C to 220 °C and heating rate 1 °/min. Under the study conditions, the boiling temperature of the test substance has been determined to be 207.7 °C +/- 0.5 °C (480.85 +/- 0.5 K) at 1019 hPa (Stannek, 2017).
