Abstract
Abstract A method of combining explosive compositions prepared from commercially available nitric acid and a common industrial solvent is disclosed herein which exhibits exceedingly high blasting strengths. The compositions are relatively more stable than conventional shaped charge explosives such as HMX or RDX and far less expensive. The compositions are transported separately to the blasting site where the compositions are combined in ambient temperature for immediate use.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
46 words
In a completely liquid and flowable explosive composition for use and mixture at the field operational site, the improvement consisting of: 28.4% to 47.18% nitroethane blended at the operation site with 53.82% to 71.6% nitric acid wherein said nitric acid contains from 25.0% to 40.05% water.
Claim 2
Dependent Claim
46 words
In a completely liquid and flowable explosive composition for use and mixture at the field operational site, the improvement consisting of: 28.4% to 47.18% nitroethane blended at the operation site with 53.82% to 71.6% nitric acid wherein said nitric acid contains from 25.0% to 40.05% water.
Claim 3
Dependent Claim
27 words
A flowable composition in accordance with claim 1 wherein: 28.4% to 41.7% nitroethane is blended with 58.3% to 71.6% nitric acid wherein said acid contains 40.0% water.
Claim 4
Dependent Claim
27 words
A flowable composition in accordance with claim 1 wherein: 33.2% to 47.2% nitroethane is blended with 52.8% to 66.8% nitric acid wherein said acid contains 25.0% water.
Claim 5
Dependent Claim
66 words
In an inexpensive, stable liquid and flowable explosive for use in field operations to be mixed at a specific site, the improvement consisting of: 28.4% to 47.2% liquid nitroethane mixed with 35.0% to 50.1% liquid nitric acid and 13.2% to 28.6% water, wherein said nitric acid is anhydrous nitric acid and said nitroethane and said nitric acid are separate ingredients mixed at said field operational site.
Claim 6
Dependent Claim
66 words
In an inexpensive, stable liquid and flowable explosive for use in field operations to be mixed at a specific site, the improvement consisting of: 28.4% to 47.2% liquid nitroethane mixed with 35.0% to 50.1% liquid nitric acid and 13.2% to 28.6% water, wherein said nitric acid is anhydrous nitric acid and said nitroethane and said nitric acid are separate ingredients mixed at said field operational site.
Claim 7
Dependent Claim
23 words
A composition of claim 4 wherein: 41.7% to 47.2% nitroethane is blended with 35.0% to 39.6% nitric acid and 13.2% to 23.3% water.
Claim 8
Dependent Claim
23 words
A composition of claim 4 wherein: 28.4% to 33.2% nitroethane is blended with 42.9% to 50.1% nitric acid and 16.7% to 28.6% water.
Claim 9
Independent Claim
81 words
A method of preparing a flowable explosive composition from only two liquid components comprising the steps of: selecting a first liquid component consisting of 28.4% to 41.7% nitroethane; selecting a second liquid component consisting of 58.3% to 71.6% nitric acid which includes 40.0% water; blending said first and second liquid components together for immediate use in field operations at a specific site; and detonating said blended two liquid component explosive composition at said specific site by a separate and individual detonation.
Claim 10
Independent Claim
81 words
A method of preparing a flowable explosive composition from only two liquid components comprising the steps of: selecting a first liquid component consisting of 28.4% to 41.7% nitroethane; selecting a second liquid component consisting of 58.3% to 71.6% nitric acid which includes 40.0% water; blending said first and second liquid components together for immediate use in field operations at a specific site; and detonating said blended two liquid component explosive composition at said specific site by a separate and individual detonation.
Claim 11
Dependent Claim
39 words
The method in accordance with the steps of claim 7 after the selection steps includes the step of: transporting and shipping said selected liquid components in separate containers to said specific operational site preparatory to said step of blending.
Claim 12
Dependent Claim
62 words
The method in accordance with the steps of claim 8 wherein said step of blending occurs at ambient temperature and is followed by the step of pouring said blended two liquid component explosive composition into openings and crevices in the terrain at said specific operational site so that it flows and occupies the openings and crevices preparatory to said step of detonation.
Claim 13
Dependent Claim
23 words
The method in accordance with the steps of claim 9 wherein: said detonation step is other than by shock or cap sensitive means.
