Abstract
Abstract Explosive compositions prepared from commercially available nitric acid and a common industrial solvent are disclosed herein which exhibit exceedingly high blasting strengths. The compositions are relatively more stable than conventional shaped charge explosives such as HMX or RDX and far less expensive.

Claim 3
Dependent Claim
26 words
A composition in accordance with claim 1 wherein: 22.0 to 32.0% nitropropane is blended with 73.9 to 78.0% nitric acid wherein said acid contains 40.0% water.
Claim 4
Dependent Claim
26 words
A composition in accordance with claim 1 wherein: 26.1 to 37.1% nitropropane is blended with 62.9 to 70.0% nitric acid wherein said acid contains 25.0% water.
