Conclusions:
The test was carried out at 97.8 kPa atmospheric pressure. Using a linear heating rate of 0.5 °C/min, the boiling point of SH-0850 was found to be 274.0 ± 0.21 °C (95 % confidence interval), i.e. 547.1 K.
Executive summary:

For the determination of the boiling point, the capillary method is used. A small amount of the test item is heated in the electronic controlled sample block and the temperature around the sample is displayed. The sample is observed visually while raising the temperature. A phase transformation from liquid to vapour usually is deduced by the formation of bubbles. The test item is assessed visually for any possible changes in its appearance, consistency and colour. The initial temperature of boiling or other effects observed is registered with the corresponding heating temperature.

 

The boiling point of SH-0850 is: 274.0 ± 0.21 °C.

The color of the test item turns into dark brown during the melting process.

Description of key information
