摘要:
The present invention relates to a lubricating composition, particularly marine diesel engine lubricating compositions, comprising: (a) an oil of lubricating viscosity; (b) an asphaltene dispersant comprising an amide group, which may also contain a succinimide group, and which may optionally be used in combination with additional asphaltene dispersants that contain a cyclic headgroup that contains a nitrogen atoms where the additional asphaltene dispersants may also include a succinimide group; and (c) a detergent derived from an alkyl phenol. The invention further provides methods of using such compositions in the operation of engine, particularly marine diesel engines.

摘要:
The present invention relates to a composition containing a particulate solid, a non-polar organic medium, and a compound obtained/obtainable by reacting an aromatic amine with hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl-substituted acylating agent is selected from the group consisting of an oligomer or polymer from condensation polymerisation of a hydroxy-substituted C10-30 carboxylic acid into a polyester, an optionally hydroxy-substituted C10-30 carboxylic acid, a C10-30-hydrocarbyl substituted acylating agent, and a polyolefin-substituted maleic anhydride. The invention further provides compositions for inks, thermoplastics, plasticisers, plastisols, crude grinding and flush.
摘要:
The present invention provides a composition and a concentrate, comprising: (a) a major amount of an oil of lubricating viscosity, (b) a quaternary ammonium salt of a hydrocarbyl-substituted acylating agent condensation product, and (c) an optional amount of a succinimide dispersant different from (b), and a use of the composition or concentrate for lubricating an engine. In a further embodiment, the invention provides the use of a quaternary ammonium salt of a hydrocarbyl-substituted acylating agent condensation product as a dispersant in a lubricating composition, and as a synergistic dispersant combination with a different succinimide dispersant.
