  • Process for synthesizing alkylated arylamines
    Publication number: 20060276677
    Abstract: An improved process and novel catalyst system for alkylating arylamines generally comprising the combination of an arylamine and an alkylating agent in the presence of a trialkyl aluminum compound and a hydrogen halide. The improved process and new catalyst system allows for higher total conversion of the arylamine feedstock without sacrificing substitution product selectivity and also allows for the reaction of recycled alkylene feedstock.

  • Oil-soluble molybdenum derivatives derived from hydroxyethyl-substituted mannich bases
    Publication number: 20060084584
    Abstract: The present disclosure relates to organic molybdenum complexes prepared by reacting a Mannich base with a source of molybdenum. The complexes may be useful in lubricating oil compositions as at least one of an antioxidant, a deposit control additive, and a friction modifier. The organic molybdenum complexes may show a reduced tendency to color finished oils.

  • Preparation of sterically hindered hydroxyphenylcarboxylic acid esters
    Publication number: 20050192455
    Abstract: A novel manufacturing process is described for producing hindered phenolic alkyl esters, which may be useful as antioxidants. This process simplifies catalyst neutralization and removal during the preparation of hindered phenolic esters. Compositions that comprise the hindered phenolic esters produced according to these methods are also described.

  • Antioxidant combination for oxidation and deposit control in lubricants containing molybdenum and alkylated phenothiazine
    Publication number: 20050090407
    Abstract: The invention relates to a lubricating oil composition having improved antioxidant properties, and which contains a molybdenum compound and an alkylated phenothiazine. Further, it may also include a secondary diarylamine, preferably an alkylated diphenylamine. This combination of additives provides improved oxidation control and friction modifier performance to the lubricating oil. The composition is particularly suited for use as a crankcase lubricant, or a transmission lubricant, including low levels and zero levels of phosphorus.
