Independent Claims | See all claims (8)

  1. 1. An additive for hydrocarbon fuels, capable of reducing smoke and carbon monoxide in exhaust gases consisting of the product of a reaction of nitrate of ammonium and anhydrous ethanol, in the presence of a nitroderivative selected from the group consisting of mono-nitrobenzene and mono-nitroalkyl (C-1-C-4) benzene or a mixture of the same at a temperature of not more than 40-45 degrees C., the nitroderivative being in a concentration of 1 to 3% by weight, the molar relation between the nitroderivatives and nitrate of ammonium being at least 0.05-0.1 to 1.
  2. 7. A process for the preparation of an additive for hydrocarbon fuels for reducing smoke and carbon monoxide in exhaust gasses consisting of the steps of:a) heating anhydrous ethanol to approximately 25 degrees C.;b) gradually adding approximately 76 grams of nitrate of ammonium per liter of anhydrous ethanol while continuously agitating the mixture;c) at a point when all of the nitrate of ammonium is dissolved in the ethanol, adding 15 milliliters of a nitroderivative per liter of ethanol selected from the group consisting of mono-nitrobenzene, mono-nitroalkyl (C-1-C-4) benzene and mixtures thereof, while continuously agitating;d) subsequently adding approximately 30 grams per liter of ethanol of a dehydrating agent in sufficient quantity to retain substantially all of the water produced during reaction, and allowing the dehydrating agent to crystallize;e) thereafter, separating the dehydrating agent.
