Lubricants and lubricant additives: I. Performance characteristics of N-mono and N,N-Disubstituted fatty amides and modified fatty amides

A number of N-mono and N,N-disubstituted amides of substituted and unsubstituted C₁₈ fatty acids have been prepared and evaluated as base lubricants and lubricant additives. The neat epithioamides possess extreme pressure lubricant characteristics and are noncorrosive at normal temperatures. The epithioamides also frequently function as extreme pressure additives and antiwear agents for paraffinic or diester base oils, sometimes in both capacities for both base oils. The intensiveness of these properties correlated directly with the degree of thiirane substitution in the compound. Performance in both these capacities at the same levels of epithioation was dependent upon the N- or N,N-substituent groups present.
