About this book

"U.S. Patent 4,293,314: Gelled Fuel-Air Explosive" by Bertram O. Stull is a scientific publication written in the late 20th century. This patent details an innovative method involving the use of 1,2-butylene oxide as a fuel for fuel-air explosive weapons. The publication is primarily focused on improving the safety and handling properties of fuel for these explosives. The content of the patent outlines the advantages of substituting 1,2-butylene oxide for traditional fuels like ethylene oxide and propylene oxide. Stull explains that this chemical is significantly less toxic and easier to handle, as it has a higher boiling point and lower vapor pressure. The document discusses both neat liquid and gelled forms of 1,2-butylene oxide, emphasizing that when gelled with agents such as silicon dioxide, it remains dispersible and safely usable in explosive applications. The patent claims improvements in safety, storage, and overall usability of fuel-air explosive devices by utilizing this new fuel option.
