Thermogravimetric Analysis of Polynitro Arenes

Attention was paid to seventeen samples of polynitro arenes. Stability of these nitrocompounds was specified by means of non-isothermal thermogravimetric analysis (TG). Linear relationships were specified between the positions of TG-onsets and the mass of the samples. The relation of slopes of the mentioned relationships to the rate constants of the thermal decomposition under condition of Russian manometric method (SMM) was confirmed and solved for studied polynitro arenes. These arene derivatives were classified into several groups in the sense of this relation. The classification was interpreted by dominating influence of intermolecular interaction factors on the corresponding TG-onsets positions. The found relations can be used for the TG results conversion to the parameters, which are comparable with SMM outputs.
