Abstract : An oxidizer that is soluble in a polar solvent selected from ethanol, diethyl ether, and acetone is used in a propellant composition mixing procedure to effect an improved dispersion of the oxidizer. The soluble oxidizer is selected from the reaction products formed by reacting together an equivalent amount of a first reactant selected from triethanol amine or diethanol amine with an equivalent amount of a second reactant perchloric acid when the soluble perclorate salt is desired for use. The soluble oxidizer is selected from the reaction products formed by reacting together an equivalent amount of a first reactant selected from triethanol amine or diethanol amine with an equivalent amount of a second reactant nitric acid when the soluble nitrate salt is desired for use. The dissolved oxidizer is added to the binder portion of the propellant during mixing. After being widely dispersed, the soluble oxidizer and binder portion are mixed under low vacuum and mild heat (e.g., 110 F. to 120 F.) to remove the polar solvent thereby leaving the oxidizer in a widely dispersed state. The other propellant ingredients are added and mixing is continued to achieve homogenity prior to forming and curing the propellant for its intended use. The propellant composition with the widely dispersed oxidizer shows improved burning rate. (Author)
