Thermal stability of σ complexes of 2,4-dinitroanisole, 2-methoxy-3,5-dinitrobenzamide, 2,4-dinitro-5- and 2,4-dinitro-6-methoxyanisole, and 1-methoxy-2,4-dinitronaphthalene with alkali metal methylates was studied by differential thermal analysis in combination with differential thermogravimetry. The temperature and heat of decomposition of these compounds depend on the nature of substituent in the anion of the σ complex and on the radius of the alkali metal cation. In the first step of the thermolysis the corresponding dinitrophenolates and dinitronaphtholates are formed. The final products of the thermolysis are alkali metal formates.
