Results and discussion

Any other information on results incl. tables

Total heat of decomposition of TMAL is 864 J/g. - The onset temperature of the decomposition effect was measured at 207°C. This was measured in a Setaram C80 scan with a heating rate of 0.1°C/min. So, the SADT of TMAL will be well above 75°C.
