Any other information on results incl. tables

A sharp melting point could not be determined due to impurities. The melt was a white pasty substance which contains amount of water.

During the test of auto-ignition temperature, a evaporation of water at 60 °C was oberved. And then the test substance melted at ca. 140 °C and changed its colour to yellow as a sign for decomposition.
