Patent ID: 8921288

Claim:
A lubricating composition comprising an oil of lubricating viscosity and a β-amino carbonyl compound of formula: wherein, independently, each variable X is —OR 6 , —HNR 6 , —N(R 6 ) 2 ; R 1 and R 2 are independently each a hydroxy-alkyl group HO-Ak′-, wherein Ak′- is an alkylene group containing 1 to 30 carbon atoms; R 3 and R 4 are hydrogen, an unsubstituted or substituted hydrocarbyl group containing 1 to 30 carbon atoms, or —C(O)—O-Ak, with the proviso that the number of total number of carbon atoms on substituent groups R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 is at least 8; R 5 is hydrogen or an alkyl group containing 1 to 8 carbon atoms, or R 1 and R 5 are joined to form a cyclic structure; Ak is an alk(en)yl group containing 1 to 30 carbon atoms; and R 6 is an alk(en)yl chain containing 1 to 30 carbon atoms.
