  • Patent number: 10246428
    Abstract: 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.

  • Patent number: 9994532
    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.
