Abstract
A process for producing an additive for hydrocarbon fuels by combining picric acid, powdered iron, an activating acid, and a liquid organic solvent. Alternatively, the powdered iron can first be washed with the activating acid and the rinsed with water or alcohol or water followed by alcohol; subsequently the washed and rinsed iron is combined with the picric acid and the liquid organic solvent. In the case of either alternative, hydroquinone can be added to the mixture in order to control undesired oxidation and corrosion, thereby further enhancing the stability of the additive.
Claims58
A process to manufacture an additive for hydrocarbon fuels, which comprises:
- combining picric acid, powdered elemental iron, an activating acid, and a liquid organic solvent and
- agitating said picric acid, said powdered elemental iron, said activating acid, and said liquid organic solvent during and subsequent to said combining.
A process to manufacture an additive for hydrocarbon fuels, comprising:
- first, washing powdered elemental iron with an activating acid;
- second, rinsing said powdered elemental iron with a rinsing agent;
- third, combining said washed and rinsed powdered elemental iron with picric acid and a liquid organic solvent;
- and
- fourth, agitating said washed and rinsed powdered elemental iron, said picric acid, and said liquid organic solvent during and subsequent to said combining.
