Patent number: 5925153Abstract: A process for producing ferrous picrate and a fuel additive containing ferrous picrate. Picric acid is dissolved in an organic solvent which has a low solubility for water. The resultant mixture is filtered and substantially all water is removed from the filtered mixture before an alcohol, preferably an alcohol which is not hygroscopic, is added to the filtered, dewatered mixture. Powdered elemental iron is added to the mixture that includes the alcohol; the reaction mixture resulting from the previous steps is preferably agitated until such reaction mixture becomes substantially homogeneous; and, if needed, sufficient water is added to the reaction mixture to create a conductive medium which enables the requisite ionic reaction to proceed at a reasonable rate. The concentration of water is, however, maintained below a level where the water causes the additive to be undesirably unstable.Type: GrantFiled: March 9, 1998Date of Patent: July 20, 1999Inventor: George Riegel

Patent number: 5720783Abstract: A process for preparing ferrous picrate is disclosed. The process includes the step of reacting under substantially non-oxidising conditions ferrous carbonate substantially free from ferric compounds with a substantially water-free solution of picric acid in a solvent medium to produce a solution of ferric picrate. The solvent medium is selected from aromatic hydrocarbon solvents, mixtures of aromatic hydrocarbon solvents, straight- or branched-chain aliphatic alcohols, mixtures of straight or branched-chain aliphatic alcohols, and mixtures of straight- or branched-chain aliphatic alcohols and aromatic hydrocarbon solvents. The reaction is preferably carried out under a continuously maintained inert atmosphere and at a temperature between 10.degree. C. and 120.degree.
