A method is disclosed for forming a stable, water-in-oil emulsion phase containing a polymeric emulsifier. The addition of an animal oil or fatty acid additive enhances the long-term stability of the emulsion phase following homogenization.

Emulsion phase having improved stability

The present invention relates to a water-based explosive having detonation properties similar to dynamite. It comprises an emulsion explosive formed by blending an emulsion phase with cast particles. The emulsion phase comprises a continuous organic liquid fuel phase, a discontinuous inorganic oxidizer solution phase and an emulsifier. The cast particles comprise a mixture of sodium perchlorate, water and diethylene glycol. The cast particles can be added to the emulsion phase before the particles are completely cured and thus before they reach final sensitivty.

High energy explosive containing cast particles

Disclosed is a process for preparing an energetic mixture of trimethylolethane trinitrate and triethylene glycol dinitrate by forming a polyol mixture of trimethylolethane, triethylene glycol and water and then nitrating the polyol mixture with a mixture of nitric and sulfuric acids.
