Abstract
Energetic compounds based on bismuth salts with reduced toxicity that are obtained through the reaction of soluble bismuth salts with soluble salts of organic or inorganic energetic compounds based on azides, derivatives aromatic nitro compounds or nitrogenous heterocyclic compounds, together with the methods for their preparation and application.
Claims15
A method for the preparation of energetic compounds based on bismuth salts with reduced toxicity, having properties of primary explosives, said method comprising reacting soluble bismuth salts with the soluble salts of organic or inorganic energetic compounds, wherein the organic or inorganic compounds are based on azides, aromatic nitro compounds, or derivatives thereof, or nitrogenous heterocyclic compounds, thereby forming a bismuth salt having a bismuch cation and an anion selected from the group consisting of an azide anion, an aromatic polynitro nitro anion, or derivative thereof, and a nitrogenous heterocyclic anion.
A method for the preparation of a soluble bismuth oxo-perchlorate salt for the production of energetic compounds based on bismuth salts with reduced toxicity, having properties of primary explosives, said method comprising:
- reacting a concentrated perchloric acid with metal bismuth and its oxides or with oxo-carbonates, thereby obtaining bismuth perchlorate;
- and
- hydrolysing the bismuth perchlorate by dilution with water, thereby obtaining the soluble bismuth oxo-perchlorate salt.
