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 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.
