    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.

    摘要翻译： 本发明涉及一种在油介质中制备高碱性金属洗涤剂的方法，包括以下步骤：（1）提供选自烃基取代的有机酸的金属盐; 烃基取代的酚，酚盐，烃基取代的羧酸酯及其混合物; （2）进一步提供甲醇和含有2至约7个碳原子的醇的混合物，其中甲醇与醇混合物的摩尔比为约2.2或更小，以形成混合物; （3）进一步提供碱性金属化合物; （4）使步骤（3）的混合物与二氧化碳反应形成碳酸化高碱性金属磺酸盐; （5）在步骤（4）的乘积上进行至少三次附加次数的步骤（3）和（4）; （6）此后除去步骤（1） - （5）中产生的水的至少一部分和步骤（2）中引入的醇; （7）再次执行步骤（2），步骤（6）的产物; （8）根据步骤（7）的乘积执行步骤（3）和（4）至少两次; 和（9）此后从组合物中除去大部分的水和醇; 其中所述油介质的存在量使得（1）的金属盐对应于油介质的酸的重量比为0.3至1.4; 并且其中当烃基取代的有机酸是烃基取代的磺酸时需要步骤（6）。 本发明还涉及其在内燃机中的应用。
