Abstract
A method and compound includes mixing a salt compound to 2-butyne-1,4-diol in an alcohol to create a mixture; adding a solution of dichloroglyoxime in an alcohol to the mixture to create 3,3'-bis-isoxazole-4,4′,5,5′-tetryltetramethanol; and nitrating the 3,3′-bis-isoxazole-4,4′,5,5′-tetryltetramethanol to create 3,3′-bis-isoxazole-4,4′,5,5′-tetrylbis(methylene) tetranitrate, which has the structural formula: The alcohol may include ethanol, wherein the adding may occur at 60° C., or alternatively the adding may occur at 80° C. The alcohol may include n-butanol, wherein the adding may occur at 100° C., or alternatively the adding may occur at 120° C. The mixing may occur at 120° C. The method may further include cooling the nitrated 3,3′-bis-isoxazole-4,4′,5,5′-tetryltetramethanol to 0° C.; stirring the cooled nitrated 3,3′-bis-isoxazole-4,4′,5,5′-tetryltetramethanol for at least four hours creating a precipitate; warming the precipitate; pouring the precipitate onto ice while stirring creating a solid material; collecting the solid material; and drying the solid material to yield the 3,3′-bis-isoxazole-4,4′,5,5′-tetrylbis(methylene) tetranitrate.
