    摘要: A lubricant composition comprising lubricating oil and a compound containing phosphorus and an amine of formula I: wherein R1 is a hydrocarbon group and at least one of R1 is selected from: —(C1-C20)alkyl, —(C1-C20)alkenyl, —(C5-C20)cycloalkyl; R is selected from: —(C4-C20)alkyl, —(C4-C20)alkenyl, —(C5-C20)cycloalkyl; and wherein R2, R3 and R4 are independently selected from: —H, —(C6-C36)alkyl, —(C6-C36)alkenyl, —(C6-C36)cycloalkyl, wherein at least one of R2, R3 and R4 is not H; X is O or S; Y1 and Y2 are selected from S and O; m is 1 or 2, n is 0 or 1, p is 1 or 2, provided that m+n+p=3 and q=0.8 to 1.2*p, wherein the compound provides at least 48 ppm of phosphorus and a molar ratio phosphorus to nitrogen (P/N) in the range of about 0.40 to about 1.50.
