Results and discussion

For thermal stability study

Test substance thermally stable:
yes
Operating temperature
Operating temp.:
30 - 600 °C
Remarks on result:
other: exothemic reaction: >980 J/g at onset temperatue 415°C

Any other information on results incl. tables

Carbon disulfide is thermodynamically unstable.

The standard enthalpy +89.7 KJ / mol.

In the literature (eg Medard, Accidental Explosions) it is stated that the self-decomposition can be initiated with appropriate boundary conditions.
By DSC measurements should be checked whether a thermal decomposition at Temperatures up to 250 ° C occurs.

Result:

A significant exothermic decomposition is only at temperatures above 400 ° C observable.
The repeated (5x) heating of a sample to 300 ° C shows no significant change in the thermogram
