  • Michael adduct amino esters as total base number boosters for marine diesel engine lubricating compositions
    Patent number: 10577556
    Abstract: A lubricating composition suited to use in a marine diesel engine includes an oil of lubricating viscosity and an amino carboxylate compound of formula (I): NR1R2—((CHR3)xNR4)n—(CHR5)2—COY, where R1 and R2 are independently selected from —(CHR6)2—COY?, H, and C1C3 alkyl and wherein at least one of R1 and R2 is —(CHR6)2—COY?; or wherein NR1R2 is a cyclic structure; Y and Y? are independently selected from —OR7, NHR7, and —N(R7)2; each R7 is independently selected from C6-C12 alkyl and C6-C12 alkenyl; R3, R5 and R6 are independently selected from H and C1-C4 alkyl; R4 is selected from H, C1-C4 alkyl, and (CHR3)xNH2; x is from 2 to 4; and n is at least 1, except where NR1R2 is a cyclic structure, where n is at least 0.
