of 1,2-butylene oxide is only 207.0 mm Hg at 25° C. as opposed to 1,292.0 for ethylene oxide and 569.0 for propylene oxide. 40

In a second embodiment of this invention, 1,2-butylene oxide may be used in a gelled state. It has been found that, if 1,2-butylene oxide is gelled by adding about 3 to about 10 weight percent of a gelling agent such as SiO2 (Cab-O-Sil), particulate carbon or aluminum 45 octoate, it will still be dispersed into a detonable cloud by a typical fuel air explosive weapon. This is perhaps the best mode of practicing this invention for several reasons. First, the gel is more easily handled than the neat liquid. Second, if spilled the gel will not 50 disperse as a liquid will.

In storage, no self-polymerization of 1,2-butylene oxide has been detected. Thus, a warhead loaded with the material has an indefinite shelf-life.

I claim: 55

1. In a method for producing an explosion comprising the steps of dispersing a cloud of liquid particles in the air and detonating the cloud, the improvement residing in utilizing 1,2-butylene oxide in gel form as said liquid.

2. A method according to claim 1 wherein said gel 60 consists essentially of 1,2-butylene oxide and a gelling agent selected from the group consisting of SiO2, particulate carbon and aluminum octoate.

3. A method according to claim 2 wherein said gelling 65 agent is present in an amount in the range of from about 3 to about 10 weight percent.
