Abstrakt:
The isobaric heat capacities of solid explosive materials were measured using differential scanning calorimeter. The values of C-p were determined at temperature 298.15 K and compared to theoretical data calculated using the group additivity approach. Several group contribution methods were tested, showing that certain method for some explosives provides estimation of C-p with error only 1 %. Generally, the average error limit for calculated C-p was about 11 %, which is insufficient.
