Nitrogen-containing products of phosphosulfurized amides and lubricants containing same

专利摘要

The invention herein is concerned with new compositions of matter made by (1) reacting phosphorus pentasulfide with an amide and (2) reacting this product with a nitrogen-containing compound, and lubricant compositions containing same. The compositions reduce friction to a greater extent than lubricants containing no additive and, when placed in lubricating oils and used in an internal combustion engine, fuel consumption is reduced. ......
