SUMMARY OF THE INVENTION
It has now been found that 1,2-butylene oxide, when used as a fuel for fuel air explosive devices, exhibits marked superiority over either ethylene oxide or propylene 60 oxide. The marked superiority stems from the fact that 1,2-butylene oxide is about 3 times safer than propylene oxide when long exposure to it is required and about 3.5 times safer than ethylene oxide. Insofar as ease of detonation is concerned, 1,2-butylene oxide has about 65 the same explosive limits as propylene oxide. However, 1,2-butylene oxide is significantly easier to handle because its boiling point is nearly twice that of propylene oxide—63° C. as opposed to 34.2° C.—and over 6 times that of ethylene oxide. According to this invention 1,2-butylene oxide may be used in either its natural 5 liquid state or gelled with a hereinafter named gelling agent.
