Insensitive plasticizer and melt-castable energetic material
A method and compound includes mixing dichloroglyoxime with an alcohol containing an alkyne functional group in methanol to create a mixture; adding a salt compound and water to the mixture to create bis-isoxazole diol; and nitrating the bis-isoxazole diol to create 3,3′-bis-isoxazole-5,5′-bis-methylene dinitrate, which has the structural formula: The alcohol containing an alkyne functional group may include propargyl alcohol. The salt compound may include sodium bicarbonate. The method may include nitrating the bis-isoxazole diol with nitric acid. The nitric acid may include at least a concentration of 90% nitric acid in water. Alternatively, the method may include nitrating the bis-isoxazole diol with 100% nitric acid and acetic anhydride. The salt compound and the water may be added to the mixture over at least a six-hour period. The method may include mixing the mixture after adding the salt compound and the water for at least ten hours.
