Abstract
Alkylamine, alkylenedi-, alkylenetri- or alkylenetetra-amine derivatives of N-alkyl-halo-acetamides, are useful as ashless, phosphorus-free and sulfur-free antiwear and friction modifying additives for lubricating oils. The additives are of the formula (I), (II) or (III) where A is alkylene of from 2 to 6 carbon atoms or is a group G, each independently, is alkylene of 2 to 6 carbon atoms, R, each independently, is alkyl or alkenyl of 1 to 8 carbon atoms and R', each independently, is hydrogen or alkyl or alkenyl or 1 to 24 carbon atoms, where if an amide nitrogen is monosubstituted by alkyl or alkenyl, said alkyl or alkenyl is from 8 to 24 carbon atoms, where if an amide nitrogen is disubstituted by alkyl or alkenyl, the total carbon atoms of said alkyls or alkenyls combined are from 8 to 18 carbon atoms, and where each amide nitrogen is either mono- or disubstituted by alkyl or alkenyl.
