Wet Mix Method Including a Secondary Fuel
[0029]A composition was made by providing a jacketed mixing vessel containing about two liters of ethanol. To this solution, about 753 grams of dinitrosalicylic acid (DNSA) was added while continuously stirring. The solution was then heated slowly to about 105 C over about thirty minutes and maintained throughout the remaining process. Once the DNSA was completely dissolved, about 4352 grams of ammonium nitrate, about 122 grams of potassium nitrate, about 227 grams of potassium carbonate (whereby potassium nitrate and potassium carbonate taken together provide a potassium source for phase stabilization of the ammonium nitrate), about 595 grams of diammonium bitetrazole, and one liter of water are added together into the vessel, while continuously and mechanically stilling. A bright yellow precipitate forms immediately in a viscous, paint-like consistency. After about one hour, the mix forms crumbly solids. The mixing and heating is continued ...

Wet Mix Method
[0030]A composition was made by providing a jacketed mixing vessel containing about two liters of water or ethanol, or any other suitable solvent such as ethers or alcohols. To this solution, an approximate stoichiometric amount of dinitrosalicylic acid (DNSA) or a metal or nonmetal salt of DNSA was added while continuously stirring. The solution was then heated slowly to about 105 C over about thirty minutes and maintained throughout the remaining process.
[0031]Once the DNSA was completely dissolved, an approximate stoichiometric amount of ammonium nitrate was added and stirred into the solution. A potassium source such as potassium nitrate was then added in about 10-15% by weight with regard to the total amount of ammonium nitrate added. The mixture was continually stirred and the heat maintained as a solid formed. The mixing and heating is continued until the desired dryness is obtained. If desired, the mix may be formed into desired shapes such as pellets or tablet...

Wet Mix Method Including a Secondary Fuel
[0032]A composition was made by providing a stainless steel jacketed mixing vessel containing about two liters of water. To this solution, about 753 grams of dinitrosalicylic acid (DNSA) was added while continuously stirring. The solution was then heated slowly to about 105 C over about thirty minutes and maintained throughout the remaining process. Once the DNSA was completely dissolved, about 4352 grams of ammonium nitrate, about 122 grains of potassium nitrate, about 227 grams of potassium carbonate (whereby potassium nitrate and potassium carbonate taken together provide a potassium source for phase stabilization of the ammonium nitrate), about 595 grams of diammonium bitetrazole, and one liter of water are added together into the vessel, while continuously and mechanically stirring. A bright yellow precipitate forms immediately in a viscous, paint-like consistency. After about one hour, the mix forms crumbly solids. The mixing and heatin...
