  • Patent number: 4747972
    Abstract: Processes of reducing the inorganic sulfur-containing acid and the low equivalent weight organic sulfonic acid content of an acid mass comprising organic sulfonic components and inorganic sulfonating agent contaminants are described. In general, the process comprises the steps of(a) treating the acid mass with ammonia in the presence of water to neutralize the acids in said acid mass and to form a mixture containing the ammonium salts of said acids,(b) allowing separation of the mixture to provide a lower aqueous phase containing water-soluble ammonium salts and an upper phase comprising the oleophilic alcohol and ammonium salts of the organic sulfonic acids, and(c) recovering at least a portion of said upper phase. The efficiency of the reduction of undesirable materials from the acid mass can be increased by subjecting the recovered upper phase to additional water extractions in the presence of the oleophilic alcohol.

  • Patent number: 4710474
    Abstract: A method which involves the isolation, analysis and characterization of dispersants present in motor oils is disclosed. The method is particularly useful in connection with the characterization of high molecular weight polybutenyl succinimide dispersants present in finished motor oils so as to provide detailed information with respect to the starting material reactants needed to synthesize such dispersants. The method involves breaking down complexation present in the oil followed by the isolation of the dispersant from the oil via dialysis. The isolated dispersant in the form of a dialysis residue is then acidified and passed through an ion exchange chromatographic column to adsorb acid materials away from the dispersant. Dispersant content and total carbonyl content can then be determined. The dispersant is then subjected to saponification with sodium hydroxide to provide a hydrocarbyl sodium succinate and a polyamine.
