RELATIONSHIP BETWEEN THE ARRHENIUS PARAMETERS OF THE LOW-TEMPERATURE THERMOLYSIS AND THE C-13 AND N-15 CHEMICAL-SHIFTS OF NITRAMINES

A linear relationship is shown to exist between the Arrhenius parameters E and log A of the initial stage of the non-autocatalysed, low-temperature thermolysis and the C-13 and N-15 chemical shifts of six nitramines. The existence of this relationship is interpreted from the point of view of the primary fragmentation in the thermolysis of the nitramines, i.e. homolysis of the N-NO2 bond. A linear relationship is also found between the heat of explosion (represented as the square of the detonation velocity and the N-15 chemical shift of the nitro groups of four of the nitramines and as well as the C-13 chemical shift in the derivatives with the methylene-nitramine grouping within their molecules.
