摘要： A new overbased metal sulphonate composition comprises a mixture of (A) at least one long chain alkyl aryl sulphonate containing an average number of at least 40 carbon atoms in the alkyl residue and (B) at least one medium long chain alkyl aryl sulphonate containing an average number of 10 to 33 carbon atoms in the alkyl residue. The composition is useful as an additive to lubricant oil.

摘要： The use of magnesium oxide of specified, low, reactivity in a process for the production of overbased magnesium sulphonates, together with the introduction of water and an alcohol, into the reaction mixture during carbonation, makes it possible to prepare high base number products which have very low post carbonation sediments and which can be purified by rapid filtration.

摘要： Overbased magnesium sulphonates having increased resistance to interactions are prepared from sulphonic acids prepared from alkylates with long and medium chain alkyl groups. Compositions comprising such overbased magnesium sulphonate are particularly suitable for use in combination with high molecular weight dispersants and/or friction modifiers. Stable sediment-free lubricating oil compositions (including lubricants and concentrates therefor) can be prepared which can meet SG quality and the Tier II fuel economy requirements.

摘要： A magnesium phenate is prepared by a process which comprises reacting (1) magnesium oxide, magnesium hydroxide, magnesium carbonate, magnesium bicarbonate or a magnesium carboxylate with (2) a phenol, a methylene bis-phenol or a sulphurised phenol in the presence of (3) a solvent comprising an organic compound containing one or more alcoholic hydroxyl groups e.g. an alkoxy alcohol and (4) a promoter selected from a ketone, diketone such as .alpha. or .beta. diketone, aldehyde or carboxylic acid and (5) optionally a diluent oil. This magnesium phenate may be used as a detergent for a lubricating oil.
