摘要： 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.The ammonium salts of the organic sulfonic acids recovered by the above process can be converted to oil-soluble metal salts by reacting said ammonium salts with a basically reacting metal compound in such amounts and under such conditions as to form metal salts of said organic sulfonic acids. The metals salts prepared in this manner may be neutral metal salts or highly basic metal salts. The neutral and metal basic salts are useful in a variety of applications including lubricants and fuels.

摘要： The invention relates to a process for preparing an overbased metal detergent in an oil medium comprising the steps of: (1) providing a metal salt selected from the group consisting of a hydrocarbyl-substituted organic acid; a hydrocarbyl-substituted phenol, a phenate, a hydrocarbyl-substituted carboxylate and mixtures thereof; (2) further providing methanol and a mixture of alcohols containing 2 to about 7 carbon atoms, wherein the mole ratio of methanol to the mixture of alcohols is about 2.2 or less, to form a mixture; (3) further providing a basic metal compound; (4) reacting the mixture of step (3) with carbon dioxide to form a carbonated overbased metal sulphonate; (5) performing steps (3) and (4) at least three additional times upon the product of step (4); (6) thereafter removing at least a portion of the water produced in steps (1)-(5) and of the alcohols introduced in step (2); (7) performing step (2) again, upon the product of step (6); (8) performing steps (3) and (4) at least two additional times upon the product of step (7); and (9) thereafter removing a substantial portion of the water and of the alcohols from the composition; wherein the oil medium is present in an amount such that the weight ratio of the acid corresponding to the metal salt of (1) to the oil medium is 0.3 to 1.4; and wherein step (6) is required when the hydrocarbyl-substituted organic acid is a hydrocarbyl-substituted sulphonic acid. The invention further relates to its use in internal combustion engines.
