Any other information on results incl. tables

The boiling temperature of the test item was identified as greater than 400 °C (673 K) at 101.6 kPa by thermal analysis. However, the test item was observed to decompose from approximately 190 °C (463 K) during heating, by visual assessment, using a modified Siwoloboff method.

The Siwoloboff method was modified in this study by not using the capillary tube known as Siwoloboff tube. The purpose of this visual test was not determining the boiling temperature but confirming the suspected decomposition of the test item. Therefore, the capillary tube was not required.
