In the lube, the low-molecular quantitative basic nitrogen content reaction product as the phosphorus/boron carrier which improves

摘要

An oil-soluble reaction product of phosphorus-, low molecular weight basic nitrogen-, and optional boron-containing compounds is provided. This reaction product can solubilize significantly more phosphorus and boron per weight of compound than other known compounds and is used as an antiwear, antioxidant, and extreme pressure additive in lubrication oils.
