PROBLEM TO BE SOLVED: To provide an additive which especially, in terms of a lubricating oil composition, increases the total base number (TBN) of a lubricant composition without increasing the ash content of a lubricant, is effective to improve the total base number (TBN) of the lubricant composition, and decreases exhaust.SOLUTION: The ashless additive for a lubricating oil composition is provided, which additive is effective to improve the total base number (TBN) of the lubricant composition. The additive includes a reaction product of NH3, alcohol, amine, or a hydrocarbyl amine with a compound represented by formula, wherein R1 is selected from H and a hydrocarbyl group. The alcohol or amine includes 1 to about 24 carbon atoms, and the hydrocarbyl amine has a number average molecular weight in the range of about 100-6,000.

PROBLEM TO BE SOLVED: To provide a lubricant which can provide the antiwear protection and viscosity protection for transmissions without harming the components of the transmission.SOLUTION: The lubricating composition includes: a major amount of an oil of lubricating viscosity; (A) an antiwear improving amount of at least one molybdenum-containing composition; (B) at least one phosphorus-containing antiwear or extreme pressure agent; and (C) at least one dispersant, provided that the lubricating composition is free of polysulfurized olefins.
摘要:
A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.
