  • Publication number: 20050137098
    Abstract: The present invention provides overbased detergents as lubricating oil additives effective for the lubrication of mechanical components in land and marine engines, such as, for example, hydraulic systems, transmissions, two-stroke and four-stroke vehicular engines, trunk piston and two-stroke crosshead marine engines. These overbased detergents lead to improved detergency and thermal stability performances versus high overbased sulfonates. Moreover, they are more compatible with commercial phenates than conventional sulfonates.

  • Patent number: 6670513
    Abstract: An alkylated hydroxyl-containing aromatic compound is produced by isomerizing a normal alpha-olefin having from about 16 to about 30 carbon atoms in the presence of a first solid, acidic catalyst capable of inducing both olefin isomerization and skeletal isomerization to produce a mixture of isomerized olefin, then alkylating an hydroxyl-containing aromatic compound with the mixture of isomerized olefins in the presence of a second solid, acidic catalyst. The first solid, acidic catalyst can be SM-3, MAPO-11, SAPO-11, SSZ-32, ZSM-23, MAPO-39, SAPO-39, ZSM-22, SSZ-20, ZSM-35, SUZ-4, NU-23, NU-87, natural ferrierite or synthetic ferrierite. The second solid, acidic catalyst can be a sulfonic acid anionic ion exchange resin catalyst or an acidic clay.

  • Patent number: 6313336
    Abstract: A process for using sludge formed in the preparation of a high BN overbased alkylaryl sulfonate or overbased sulfurized alkylphenate, wherein the sludge is treated with an acidic reactant to convert large particles of the alkaline earth metal salt in the sludge into calcium sulfonate, then is reacted with an excess of alkaline earth base and either alkylaryl sulfonic acid or alkylphenol to produce a reaction product, which could be a low or high overbased alkylaryl sulfonate or overbased sulfurized alkylphenate.
