## Abstract

An explosive composition comprising a high density hydrocarbon compound selected from the group consisting of xylitol, sucrose, mannitol, and mixtures thereof and at least one energetic material. The high density hydrocarbon compound and the at least one energetic material form a substantially homogeneous explosive composition. A method of producing an explosive composition that is insensitive to impact is also disclosed.

## Claims

at least one high density hydrocarbon compound selected from the group consisting of xylitol, sucrose, and mannitol; and
at least one energetic material selected from the group consisting of trinitrotoluene, cyclo-1,3,5-trimethylene-2,4,6-trinitramine, cyclotetramethylene tetranitramine, hexanitrohexaazaisowurtzitane, 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.05,9.03,11]-dodecane, and 1,3,3-trinitroazetine,
wherein the at least one high density hydrocarbon compound and the at least one energetic material form a substantially homogeneous explosive composition.

### Claim 2 (depends on 1)

The explosive composition of claim 1, wherein the at least one energetic material comprises trinitrotoluene.

### Claim 3 (depends on 2)

The explosive composition of claim 2, wherein the at least one energetic material further comprises cyclo-1,3,5-trimethylene-2,4,6-trinitramine or cyclotetramethylene tetranitramine.

### Claim 4 (depends on 1)

The explosive composition of claim 1, wherein the at least one energetic material is present in the explosive composition in an amount ranging from approximately 40% by weight of a total weight of the explosive composition to approximately 95% by weight of the total weight of the explosive composition.

### Claim 5 (depends on 1)

The explosive composition of claim 1, wherein the at least one high density hydrocarbon compound is present in the explosive composition in an amount ranging from approximately 5% by weight of a total weight of the explosive composition to approximately 60% by weight of the total weight of the explosive composition.

### Claim 6 (depends on 1)

The explosive composition of claim 1, wherein the explosive composition has a viscosity ranging from approximately 7 centipoise to approximately 2500 centipoise.

### Claim 7 (depends on 1)

The explosive composition of claim 1, wherein the at least one energetic material consists of cyclotetramethylene tetranitramine and the at least one high density hydrocarbon compound consists of sucrose.

### Claim 8 (depends on 1)

The explosive composition of claim 1, wherein the at least one energetic material consists of trinitrotoluene and the at least one high density hydrocarbon compound consists of xylitol.

### Claim 9 (depends on 1)

The explosive composition of claim 1, wherein the at least one energetic material consists of trinitrotoluene and cyclotetramethylene tetranitramine, and the at least one high density hydrocarbon compound consists of xylitol.

### Claim 10 (depends on 1)

The explosive composition of claim 1, wherein the at least one energetic material consists of trinitrotoluene and cyclo-1,3,5-trimethylene-2,4,6-trinitramine, and the at least one high density hydrocarbon compound consists of xylitol.

### Claim 11 (depends on 1)

The explosive composition of claim 1, wherein the at least one energetic material consists of trinitrotoluene and the at least one high density hydrocarbon compound consists of sucrose.

### Claim 12

An explosive composition consisting of trinitrotoluene and a high density hydrocarbon compound selected from the group consisting of xylitol, sucrose, mannitol, and mixtures thereof.
