摘要: An ashless additive for lubricating oil compositions, compositions and methods that are effective to improve the total base number (TBN) of a lubricant composition. The is reaction product compound formula: (see above formula) with NH3, an alcohol, amine, or hydrocarbyl wherein R1 selected from H, group, alcohol amine contains 1 about 24 carbon atoms, has average molecular weight ranging 100 6000
