Synthesis of Cobalt(III) Ammine Complexes as Explosives for Safe Priming Charges

Physicochemical and explosive properties of Co(III) pentammine complexes containing in the inner coordination sphere monodentate polynitrogen heterocyclic ligands, 1-methyl-5-aminotetrazole and 1,5-diaminotetrazole, were studied, and it was shown that these compounds can be used in priming charges.     

Influence of cation structure on decomposition of diacyl peroxides activated by chloride salts of amines

A kinetic study has been made of the interaction of benzoyl peroxide with a number of chloride salts of amines. It is shown that a change of the cation in quaternary ammonium salts does not have any significant effect on the kinetic parameters of the reaction. By means of NMR spectroscopy it has been determined that the structure of the NR₄ ⁺ cation does not change during the course of the reaction. The role of the cation in the process of activation of a diacyl peroxide by chloride salts of amines has been investigated by means of MNDO calculations.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 28, No. 4, pp. 324–328, July–August, 1992.     

Some Reactions of 3,6-Bis(4-amino-1,2,5-oxadiazol-3-yl)-1,4,2,5-dioxadiazine

Diazotization and nitration of 3,6-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,4,2,5-dioxadiazine gave, respectively, 3,6-bis(4-azido-1,2,5-oxadiazol-3-yl)-1,4,2,5-dioxadiazine and 3,6-bis(4-nitroamino-1,2,5-oxadi-azol-3-yl)-1,4,2,5-dioxadiazine. The latter reacted with nitrogenous bases to form the corresponding salts.     

Environmental problems and their solutions of using energy-rich substances for initiating devices

The current state of the problem of replacing the primary explosives used in industrial products for more secure and the necessity of such a change because of the high toxicity of metals currently used in standard means of initiation are discussed. Problems of toxicity of metals used in the primary explosives are also addressed.

Mechanisms of Initiated Protein Peroxidation Accompanied by Generation of Carbonyl Fragments

Regularities of the peroxide fragmantation of human serum albumin, initiated by an iron(II) salt and hydrogen peroxide, are considered. A chain mechanism is proposed for this process, leading to generation of carbonyl fragments of the protein molecule.
