Any other information on results incl. tables

The substance decomposes exothermally at a temperatur of 179°C (DSC-Method, 5 K/min). The decomposition energy is -467 J/g.

Decomposition is observed in an open test tube during a storage over 24 h in the temperature range 120 -160°C.

In an autoclave test a strong rise in pressure was observed at heating to 190°C (5 K/min).

For safety reasons the substance should not be handled or stored at temperatures above 60°C/24 h.
